One that transports or conveys. A charge-carrying entity, especially an
electron or a hole in a semiconductor.
Electron:
A subatomic particle in the lepton family having a rest mass of 9.1066e-28
grams and a unit negative charge of approximately 1.602e-19 coulomb.
Hole:
A vacant electron energy state that is manifested as a charge defect in
a crystalline solid, the defect behaving as a positive charge carrier with
charge magnitude equal to that of the electron.
Dopant:
A small quanitity of a substance, such as phosphorus, added to another
substance, such as a semiconductor, to alter the latter's properites.
