Under the influence of electric filed, which of the following statements is true about the movement of electrons and holes in a p-type semiconductor ?

Answer»

Electron will move TOWARDS the posiitively charged plate through electron holes.
Holes willappear to be moving towards the negatively charged plate.
Both electrons and holes appear to move towards the POSITIVELY charged plate.
Movement of electrons is not RELATED to the movement of holes.

Solution :( c)is wrong because eelctrons move towards anode while anode while holes move towards cathode. (d)is ALSO not true for the same reson.
