https://doi.org/10.1057/9780230371743n.—The theory of impact ionization shows that the energy required is somewhat greater than the optical ionization energy. Beyond the critical energy the ionization rate increases with the square (or cube) of the excess energy.

Electron and ion motion in oxide cathodes,as other constituents of the oxide, are mobile at the normal operating temperature of the cathode, and (5) electrolysis of the donors limits the density of free electrons available for conduction near the emitting surface and the density of free electrons available for emission at the emitting surface.

Der p-n-Photoeffekt,emiconductor surface, and c) the surface recombination. Thus, rules are obtained for the optimal design of a photo-cell matched to the light of a given spectral distribution, for example sunlight. Experimental results are pointed out.
