Question

When a piece of pure silicon is doped with aluminium, then
A) the conductivity of the doped silicon piece will remain the same B) the doped silicon piece will become n-type C) the doped silicon piece will become p-type D) the resistivity of the doped silicon piece will increase

Answer 1

Answer:

When a piece of pure silicon is doped with aluminium, then

A) the conductivity of the doped silicon piece will remain the same B) the doped silicon piece will become n-type C) the doped silicon piece will become p-type D) the resistivity of the doped silicon piece will increase

Answer 2

Answer:

Explanation:

Ans c .. since aluminium is a13 group element so when silicon is doped with aluminium there will a hole left it will behave as apostive charge hence become p semiconductor
