Q:

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 & Explanation Answer: C) the doped silicon piece will become p-type

Explanation:

p type of semiconductor is obtained when Silicon is doped with a trivalent impurity like Aluminium. Aluminium is a p-type dopant, which means that when a semiconductor i.e. silicon is doped with aluminium, it creates a hole (positively charged carrier) by accepting an electron from the silicon atom. Electrical conductivity of semiconductors increasesand resistivity remains the same
