Q. A p-type semiconductor can be obtained by adding

Odisha JEEOdisha JEE 2010Semiconductor Electronics: Materials Devices and Simple Circuits

Solution:

Atoms having 3 valence electrons such as Indium ( ln) or Gallium (Ga). Such atoms on being added to a pure semiconductor, instead of producing free electrons, accept electrons from the semiconductor. for this reason, trivalent impurity atoms are called acceptor impurity atoms. The semiconductor so produced is called p-type semiconductor.
