P type impurities examples
WebFor example, when silicon (Si), having four valence electrons, needs to be doped as a p-type semiconductor, elements from group III like boron (B) or aluminium (Al), having three valence electrons, can be used. The latter elements are also called trivalent impurities. Other trivalent dopants include indium (In) and gallium (Ga). WebA large number of holes are provided in the semiconductor material by the addition of trivalent impurities like Gallium and Indium. Such types of impurities which produce p-type …
