1.	A group 14 elements is to be converted into n- type semiconductor by doping in with a suitable impurity. To which group shouyld theis impurity belong ?
Answer» n-type semiconductor means increase in conductivity due to precence of excess of electrons. Therefore , a 14 group element should be doped with a 15-group element Eg. Arsenic or phosphorsus.
