Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- A tunnel diode is a highly doped semiconductor diode.
- The p-type and n-type semiconductor is heavily doped in a tunnel diode due to a greater number of impurities. Heavy doping results in a narrow depletion region.
- When compared to a normal p-n junction diode, tunnel diode has a narrow depletion width.
- The Fermi level moves in the conduction band on the n-side and inside the valence band on the p-side.
- Below the Fermi level, all states are filled and above the Fermi level all states are empty
The tunnel diode is represented by the symbol
