Abstract : It is noted that the electrical parameters of crystalline semiconductor diodes and their stability are determined to a significant degree by the condition of the semiconductor surface. Analysis of the results of studies in this area is given. The following basic means of treating the surface of semiconductors were determined to stabilize the parameters of the devices and to protect the surface from the effect of the surrounding medium: (1) passivation of the surface, i.e., creating inorganic compounds on the semiconductor surface; (2) treating the semiconductor surface with organic materials; and (3) coating the semiconductor surface with glasses of special composition. This problem cannot be solved by empirical methods until the mechanism of the formation and variation of surface charge is understood and the complex nature of surface and contact phenomena accompanying adsorption processes is studied.
