What is the charge on a p-type and n-type semiconductor?

Germanium can be made an n-type semiconductor by doping it with pentavalent impurity, like phosphorus (P), arsenic (As) or antimony (Sb).

1. In a p-type semiconductor, holes are majority charge carriers.  2. When a p-type semiconductor is connected to terminals of a battery, holes, which are not actual charges, behave like a...

p type of semiconductor is formed by adding electron deficit impurities like group 13 elements. Hence correct option is (C) Adding appropriate electron deficit impurities

Correct option is  A) qvB

(B) radially outward, radially inward

1. These are materials doped with pentavalent impurity (donors) atoms.  2. Electrical conduction in these materials is due to majority charge carriers i.e., electrons.  3. The donor atom loses electrons and becomes...

p-type semiconductor n-type semiconductor 1. The impurity of some trivalent element like B, Al, In, etc. is mixed with semiconductor. The impurity of some pentavalent element like P, As, Sb, etc. is mixed 2....

1. No.  Any slab, howsoever flat, will have roughness much larger than the inter-atomic crystal spacing (~2 to 3 Å). 2. Hence, continuous contact at the atomic level will not be possible....

(D) number of electrons and holes increases equally.

(C) missing electron in valence band.
