Description : State the impurities for obtaining p-type and n-type semiconductor from intrinsic semi conductor. 

Last Answer : Crystals of Silicon and Germanium are doped using two types of dopants:  1. The impurities for obtaining n-type semiconductor from intrinsic semiconductor are pentavalent impurity; like Arsenic (As), Antimony ... semiconductor are trivalent impurity; like Indium (In), Boron (B), Aluminum (Al), etc.
