Tunnel Diode Energy Band Diagram Explanation

- January 23, 2019

Explanation of tunneling with the help of energy band diagram when the p type semiconductor is heavily doped then the concentration of holes is higher. Another thing we need to remember is that the valence band and conduction band energy levels in the n type semiconductor are slightly lower than the valence band and conduction band energy levels in the p type semiconductor.

Tunnel diode energy band diagram explanation. Explanation of tunnel diode on the basis of energy band diagram part 2. The energy band diagram for a heavily doped unbiased p n junction is shown in fig. Explanation of tunnel diode on the basis of energy band diagram part 2.

To enroll in courses follow best educators interact with the community and track your progress. The values for these voltages depend upon the diode material and also upon its individual characteristics. A tunnel diode is a heavily doped p n.

While in heavily doped n type semiconductor the concentration of electrons is higher. 10a note that the depletion region is very narrow and the filled levels on the n side are exactly opposite those on the p side. This has a form of n shaped curve.

If the energy diagram of a tunnel diode in which the forward bias has been increased even further then the energy bands no longer overlap and the diode operates in the same manner as a normal pn junction. With an area of negative resistance between the peak voltage vpe and the valley voltage vv. The diagram towards the top of the page shows the tunnel diode iv characteristic.

Band diagrams of a tunnel diode. To enroll in courses follow best educators interact with the community and track your progress. Schottkey diode and ohmic contact in hindi 1021.

Draw the energy band diagrams of a tunnel diode for different biasing conditions. In tunnel diode the valence band and conduction. Explanation of tunnel diode on the basis of energy band diagram part 2.

On the contrary the concentration of electrons is lower. Explanation of tunnel diode on the basis of energy band diagram part 1. The portion of the curve between peak point and valley point in which current decreases as the voltage increases is the negative resistance region of the tunnel diode.
