A small amount of a trivalent impurity was introduced into a tetravalent semiconductor. What type of semiconductor is it? What is this impurity called?

When a trivalent impurity, for example, In, is added to a tetravalent semiconductor, holes are formed in the semiconductor. Such impurities are called acceptor, and semiconductors with acceptor impurities are called p-type semiconductors. In these semiconductors, holes are the majority carriers, and electrons are minority carriers.
