Question

on adding pentavalent impurity to a semiconductor_______type of semiconductor is obtained. ​

Answer 1

Answer:

When pentavalent impurity (group V) is added, it forms four covalent bonds which give free electrons to the semiconductor. As electrons are negative, it produces n type semiconductor. P-type impurities are called acceptors and n-type semiconductors are called donors as it gives free electrons to the semiconductor.
