Under the influence of electric field, which of the following statement is true about the movement of electrons and holes in a p-type semiconductor ?
(a) Electron will move towards the positively charged plate through electron holes
(b) Holes will appear to be moving towards the negatively charge plate
(c) Both electrons and holes appear to move towards the positively charged plate
(d) Movement of electrons is not related to the movement of holes
Answers: (a), and (b)
In the p-type semiconductor, the conductivity is due to the existence of a hole. When the electric field is applied to p-type semiconductor hole starts moving towards negatively charged plate and electron towards the positively charged plate.
