Question

How would you change a diamond to make it a p-type semiconductor?

Choose one:

You can't make a diamond a semiconductor.

Replace some of the carbon atoms with silicon atoms.

Replace some of the carbon atoms with phosporous atoms.

Replace some of the carbon atoms with aluminum atoms.

Answer 1

Answer #1

Diamond is made up of carbon.
Carbon have 4 valence electrons.

To make p type semiconductor, we need to dope it will element which has less than 4 valence electrons.

Silicon has 4 valence electrons.
Aluminium has 3 electrons.
Phosphorous has 5 electrons.

So, doping with Aluminium will make it p type

Answer: Replace some of the carbon atoms with aluminum atoms.
