If you are a final year student having backlogs in few subjects of your engineering degree, you can join us for B Tech coaching in Delhi to clear the subject. We guarantee you to clear the subject in one attempt. In other institutes where B Tech tuitions are provided in Delhi, the faculty members are generally school level teachers. They may be diploma level or giving tuitions to students on part time basis. Many times students tell us that faculty gives us timings at about 3 pm or 9 pm in night. They don’t give us timings on Saturday or Sunday. The reason behind this is that they assume the B Tech tuitions as a part time job. So they don’t give their prime time to B.Tech students they only give you left over hours those were suppose to be wasted. Teachers are not perfect in any subject they used to teach reading line by line from book. We here at our academy are purely Engineering level faculty, we don’t teach any school level coaching, and we do not require to refer books all the time. We give coaching with a command on subject and having all the knowledge on our tips. B Tech coaching in Delhi that we give is highly efficient both in time and result oriented. In many cases we see that such school level teacher used to charge a huge amount of fees for giving poor level B Tech coaching in Delhi. This is because they think that we have to first self study the subject then only we can let the student understand the concept. But here we have less fees and efficient faculty those are lectures of engineering colleges. Students are coming to us from far off places like, lakshmi nagar, East Delhi, West Delhi, north Delhi, Sarojinin nagar etc for taking B Tech tuition in Delhi for subjects like Maths, Physics, Electronics Devices, Electrical Technology, Signal system, Digital signal processing, EMFT, microprocessor and microcontroller. Students of final year are searching for B Tech tuition classes for their backlog subject becase they have to clear all the papers for getting the placement. We have special arrangements for final year students where they can attend classes in the form of crash course to complete the syllabus in short time. There are working professionals those are searching Engineering  tuitions in Delhi for difficult subjects like Microprocessor, ADA, TOC etc. We successfully cleared all the backlogs and all the working professionals are quite satisfied. If you are a working professional or a distant student living in far off place you can contact us at 9899927912 to set the demo class of any engineering subject.

We are giving short term course comprising of many benefints. Here we are giving the complete theory numerical practice by highly expert faculty on one to one basis. You cannot find such an expert technical faculty in any other institute. Most of the faculties are M.Tech and Phd in their fields. They have more than 10-15 years of experience. We follow standard books and teachers give introduction to subject, practice of numerical, and derivations in very easy and friendly manner. You will acquire a great confidence of the difficult subject of the coming semester and it will remove any chance of getting backlog of the subject. In these days it is found that the time available for study in any given semester is very less.Students generally don’t give much time to difficult subject as a result it gives poor preparation and cause of less marks, or backlog. You can act proactively by taking B Tech coaching in Delhi from our institute and get a chance of be the topper in your subject. Getting good marks in B.Tech subjects will help to get you shortlisted for the upcoming placements rounds for dream companies. The purpose of doing B.Tech from a reputed university or college is the desire of having a good job with a handsome package. This is possible with good percentage of marks in the Final degree marksheet. Taking B Tech coaching in Delhi in summer vacation from our institute will increase your chances for the same. You are most welcome at our academy and you can take a free demo class by calling to our number 9899927912,

Brief :-

One of the first uses of semiconductor materials was to join a p type material with an n type to form a simple but important semiconductor device called a diode.

The term diode denotes a two electrode device. As semiconductor diode is simply a PN junction with connecting leads or terminals on the two sides of the pn junction. PN junction is also called the crystal diode because the pn junction is grown out of crystal.

Please note In this B Tech coaching lecture we are going to provide you printed notes.

A diode is unidirectional device permitting the easy flow of current in one direction but restraining the flow in opposite direction. A major application of diodes is in rectification i.e. in conversion of ac into dc.

Please note Tejas Engineers Academy is dedicated to provide you all subjects B Tech coaching in Delhi.

Semiconductor diode is becoming more an more popular these days due to its smaller size, cheapness robustness and higher operating efficiency.

We request you to Check for more free lectures of B Tech coaching on our Academy website.

The p type material of the diode is the positive electrode and is called the anode whereas the n type material is the negative electrode and is called the cathode. The arrow symbol used for the anode represents the direction of flow of conventional current. The electron current flows in a direction opposite to the arrow.

The diodes have polarity and therefore, must be connected in circuits in the correct direction. Small diodes are marked with a band to indicate the cathode end. Larger diodes use the diode symbol to indicate the cathode end. Larger diodes use the diode symbol to indicate their polarity.

Please note Analog Electronics is one of the difficult subject for which students used to seek B Tech coaching.

Diodes and transistor numerical problems are covered in Detail here at Tejas Engineers Academy.

Diodes are available in many package configurations, depending on their rating. Small diodes, used for low current application in circuits up to 1 A of average current, are generally packaged in a simple glass or plastic tube. Diodes for handling larger currents are packaged  in metal containers and are often mounted by studs on metal plates to dissipate heat.

Analog Electronics is a core subject Mr. Bhagatveer Singh. He has done B.Tech and M.Tech from Delhi and he is working as a regular faculty in Tejas Engineers Academy and is providing B Tech coaching in Delhi from last 8 years. Following article is provided by Mr. Bhagatveer Singh.

Structure of pn junction

Most semiconductor devices employ one or more PN junction. The PN junction is the control element for the performance of all semiconductor devices such as rectifiers, amplifiers, switching devices, linear and digital integrated circuits. The PN junction is produced by placing a layer of P type semiconductor next to the layer of N type semiconductor. The interface separating the N and P regions is referred to as the metallurgical junction.

The p type semiconductor block has mobile holes and the same number of fixed negative acceptor ions. Similarly the n type semiconductor block has mobile or free electrons and the same number of fixed donor positive ions. Normally the holes, which are the majority charge carriers in p type of material, are uniformly distributed thorough the volume of that material. Similarly the electrons, which are the majority charge carriers in n type of material, are uniformly distributed through the volume of that material. Each region is electrically neutral because each of them carriers equal positive and negative charges.

On the formation of PN junction some of the holes from p type material tend to diffuse across the boundary into n type material and some of the free electrons similarly diffuse into the p type material. This happens due to density gradient (as concentration of holes is higher on p side than that on n side and concentration of electrons is higher on n side than on the p side). This process is known as diffusion.

As a result of the displacement of the charges, an electric field appears across the junction. Equilibrium is established when the field becomes large enough to restrain the process of diffusion. The electric charges are confined to the neighbourhood of the junction and consists of immobile ions. We see that the free electrons crossing the junction create negative ions on the p side by giving some atoms one more electron than their total number of protons. The electrons also leave positive ions behind them on the n side. As negative ions are created on the p side of the junction, the p side acquires a negative potential. Similarly the positive ions are created on the n side and the n side acquires a positive potential. The negative potential on the p side prevents the migration of any more electrons from the n type material to the p type material. Similarly the positive potential on the n side prevents any further migration ofholes across the boundary. Thus, the initial diffusion of charge carriers creates a barrier potential at the junction.

The region around the junction is compleltely ionsed. As a result there are no free electrons on the n side, nor there holes on the p side. Since the region around the junction is depleted of mobile charges it is called the depletion region, the space charge region, or the transition region. The thickness of the depletion region, is of the order of 1 micron.

The variation of electric field constitutes a potential energy barrier against the further diffusion of holes across the barrier.

The necessity for the existence of a potential barrier called the contact, or diffusion potential is now considered further. Under open circuited condtions, the net hole current must be zero. If this statement were not true, the hole densit at one end of the semiconductor would contine to increase indefinitely with time, a situation, which is obviously physically impossible. Sie the concentration of holes in the p side is much greater than that in the n side, a very large diffusion current tends to flow across the junction from the p type material to the n type material. Hence an electric field must build up across the junction in such a direction that a drift current will tend to flow across the untion from the n side to the p side in order to counterbalance the diffusion current. This equilibrium condition of zero resultant hole current allows us to determine the height of the potential barrier in terms of the donor and acceptor concentrations. The magnitude of barrier potential V is of the order of few tenths of a volt.

Barrier voltage depnds on doping density, electronic charge and temperature. For a given junction, the first two factors are fixed, thus making barrier potential dependent on temperature. Increase in temperature creates more minority charge carriers leading to their increased drift across the junction. These extra minority charge carriers reduce the width of the depletion layer equivalent to reduction in potential barrier. It is found that for either silicon or germanium diodes, the barrier potential decreases for each Celsius degree rise.
