Question

1.Why does diamond behave like as insulator ?
2.Name the charge carriers in conductor,intrinsic semiconductor and insualtor at room temperature .

Answer 1

in diamond each carbon atom is covalently bonded with four other carbon atoms and there are no free electrons.and electricity is conducted in a crystal when electrons are relatively free so it behaves like an isolator .
The main effect of temperature on an intrinsic semiconductor is that the concentration of electrons in the conduction band dramatically changes. It increases with an exponential factor with increasing temperature it decreases with temp
