Question

what is difference in the semi conductor obtained by doping silicon with Al and with p ?​

Answer 1

Answer:

Boron has atomic number 5. It has 3 electrons in its outer orbit, i.e. 3 valence electrons. Elements with 3 valence electrons are used for p-type doping and 5-valence electrons for n-type doping. Hence when Boron is doped with Silicon, it creates p-type doping.

Hope it helps

thank you

have a great day ahead

Answer 2

Explanation:

On doping with Al we get n type semiconductor

On doping with Si we get p type semiconductor
