Under the influence of the electric field, which of the following statements is true about the movement of electrons and holes in a p-type semiconductor?
(i) Electron will move towards the positively charged plate through electron holes.
(ii) Holes will appear to be moving towards the negatively charged plate.
(iii) Both electrons and holes appear to move towards the positively charged plate.
(iv) Movement of electrons is not related to the movement of holes.
The answer is the option (i, ii) In p-type semiconductor, holes act as the charge carriers. On exposure of P-type semiconductor to electric field, positively charged hole starts moving towards negatively charged plate while the electron towards positively charged plate.
