The influence of certain energy-spectrum features of disordered semiconductors on their static dielectric characteristics is studied. It is shown that under certain conditions, a material of this kind may be similar in some degree to a multidomain ferroelectric: spatial regions with a finite polarization factor appear in it at zero strength of the average (in the sense of macroscopic elec trodynamics) electric field. The influence of temperature on phase transitions of this type is investigated, and possible effects of illumination and sound are indicated.
