Question

N type semiconductor is obtained by doping intrinsic germanium with phos phorous oraluminium or boron or gold

Answer 1

⭐⭐⭐ Hey mate!!⭐⭐⭐

__________________________________________________________

♐⚡in n type semiconductor doping atoms are pentavalent that is eg(p,As) donate electrons so they are also known as doner type impurity atom.❄️

♐♐in n type semiconductor majority

charge carriers are free electrons and minority charge carriers are holes.❄️

⚡⚡So, here in given options only phosphorus is pentavalent..❄️

⭐⭐Your answer is doping wid phosphorus.

Hope it will help you...✌️✌️
