Which best describes an example of a p-type semiconductor?

a) it uses arsenic so that the electrical conduction is due to the movement of electrons.

b) it uses arsenic so that electrical conduction is due to the movement of a positive charge.

c) it uses boron so that electrical conduction is due to the movement of electrons.

d) it uses boron so that electrical conduction is due to the movement of a positive charge.

D) It uses boron so that electrical conduction is due to the movement of electrons

D) It uses boron so that electrical conduction is due to the movement of a positive charge.

Explanation:

In p type semiconductor we have to add impurity which will enhance the number of holes in the pure semiconductor.

Here we know that semiconductors are device in which conductivity is very small as compare to conductors.

Now when we add some impurity of trivalent valency in it then the number of holed in such conductors will increase due to which conductivity will increase in semiconductors

SO here since Boron is the element in which its outermost shell has 3 electrons and when it is added to the semiconductor then it will add one hole per boron atom

this will increase the conductivity due to increase in the number of holes

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
