With reference to semi-conductors answer the following$:$

$\left(\mathrm{ii}\right)$ Name the majority charge carriers in n$‐$type semi$‐$conductor.

With reference to semi-conductors answer the following$:$

$\left(\mathrm{iii}\right)$ What is meant by doping?

State anyone difference between the energy band diagram of conductors and that of insulators.
