Popis: WHEN the principle of mass action is applied to explain the effect on the electrical properties of certain electronic semi-conductors having an ionic lattice structure, produced by varying the vapour pressure of one of the constituents of the substance, it is found that nf = KPυ1/n, (1) where nf is the concentration of charge carriers, which may be free electrons or holes, K is an equilibrium constant, Pυ is the vapour pressure, and n is a constant, negative for excess and positive for defect semi-conductors, which can be deduced from the chemical structure of the substance.
