A small impurity is added to germanium to get a p-type semiconductor. Identify the impurity? Correct Answer Trivalent substance

A trivalent impurity added to germanium produces a p-type semiconductor. Trivalent impurities such as boron, indium, and gallium are called acceptor impurity. These can be added to germanium in order to obtain a p-type semiconductor.
