Question

If $Si$ is doped with $B$ ,

n-type semiconductor is formed

p-type semiconductor is formed

insulator is formed

polymer is formed

Answer

p-type semiconductor is formed

Explanation

Solution

Silicon belongs to group 14, it is doped with a group 13 element like B which contains only three valence electrons. The place where the fourth valence e is missing is called electron hole. Under the electric field, e holes moves toward the negatively charged plate, which implies that e holes are positively charged, thus it is a p-type semiconductor.
