Horizon

Introduction,nductor (PbS) was discovered by F. Braun in 1874 [311], and used in the early stages of the development of point-contact crystal detectors in radio engineering. The photovoltaic effect at a metal — semiconductor contact was also observed and exploited in lead chalcogenides.

Book 1970y spectrum of electrons is much more complex than had originally been predicted: in many cases, there are several energy bands with different parameters. It has been found that the effective carrier mass, which had been assumed to be constant for a given material, depends on the carrier energy, temp

Synchronism

Physicochemical Properties, described by the general formula A.B.. The physicochemical properties of lead chalcogenides have much in common: they are isomorphous, have the same type of chemical binding, can be prepared by methods which are (in many respects) similar, have similar phase diagrams, and can be doped in a similar manner.
