Region which have no free electron and holes in P-N junction is

Region without free electrons and holes in p - n junction is

The depletion layer in P-n junction region

An n-type semiconductor is the one which has excess of free electrons and p-type semiconductor is deficient in these. When a p-n junction is formed, the electrons should flow from n to p region. But all the electrons do not do so. Explain, why.

The ratio of number density of free electron and hole in p-type semiconductor is …….

Which one of the following diagrams depicts the proper flow or electrons and holes in a forward biased p-n junction diode?

The width of the depletion region in a P-N junction diode is

Druing P-N junction formation when the electron and holes stops moving from P to N and N to P, then
