Draw the energy band diagrams of a tunnel diode for different biasing conditions.
Band Diagrams of a Tunnel diode: The energy band diagram for a heavily doped unbiased P-N junction is shown in fig. 10(a) Note that the depletion region is very narrow and the filled levels on the N-side are exactly opposite those on the P-side. In this condition, no tunneling occurs, as there are no empty lower energy levels to which electrons from either side might cross the depletion region. It's also to be noted that conduction and valence bands on p- side are (negatively) higher than those on the n side, this is because of the formation of depletion region and barrier potential as a result of electrons crossed from n-region to the p-region. N-region has lost negative charge and p-region has gained them.
Energy gap: 1.4ev at room temperature Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and a

A wave is a disturbance which transmits power and momentum from one place to the other without the transport of matter.
Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
