Question

what are p type and N type semiconductor materials?

Answer 1

p type have more electrons and are doped with 15th group elements

n type have more holes and are doped with 13th group elements

Answer 2

When trivalent species is doped with silicon then holes are generated and such type of conductor is known as p type conductor .

Similarly when pentavelent species is doped with semi conductor then n type conductor is formed
