Silicon is the most widely used semiconductor material for integrated circuits. Which of the following are less common semiconductor materials used for ICs (two best answers) : (a) boron, (b) boron nitride, (c) gallium arsenide, (d) germanium, (e) silicon carbide, (f) silicon dioxide, and (g) zirconium?

c) gallium arsenide, d) germanium

Explanation:

Silicon is the mostly used semiconductor material which used in integrated circuits, because it have some unique properties which make it so useful in electronics industries.

Silicon also can use as insulator as well as conductor. It is generally found in earth crust.

Gallium arsenide and germanium are material which have less used in integrated circuit.
