hole
In semiconductors, free charge carriers are electrons and electron holes (electron-hole pairs). Electrons and holes are created by the excitation of an electron from the valence band to the conduction band. An electron-hole (often simply called a hole) is the lack of an electron at a position where one could exist in an atom or atomic lattice.
A hole is a positive charge carrier in a semiconductor which materially does not exist. A hole is the absence of an electron moving in the direction opposite to that of an electron and carrying a positive charge.
