There are two semiconductor materials A and B which are made by doping germanium crystal with indium and arsenic respectively. As shown in the figure, the junction of two is biased with a battery. Will the junction be forward bias and reverse bias?
As, semiconductor A is doped with indium, so it behaves as p-type semiconductor and B -is doped with arsenic so, it behaves as n-type semiconductor. Thus, the figure shows that it is forward bias condition.
