The electron concentration in an -type semiconductor is the same as hole concentration in a -type semiconductor. An external electric field is applied across each of them. Compare the currents in them.
Current in -typeCurrent in -type
Current in -typeCurrent in -type
Current in -typeCurrent in -type
No current will flow in -typecurrent will only flow in -type
To solve this problem, we need to compare the currents in an -type and a -type semiconductor.Given that the electron concentration in the -type is the same as the hole concentration in the -type.Let's denote:
