жартылай өткізгіш

жартылай өткізгіш

A material whose resistivity is between that of insulators and conductors. The resistivity is often changed by light, heat, an electric field, or magnetic field. Current flow is often achieved by transfer of positive holes as well as by movements of electrons. Examples include germanium, lead sulfide, lead telluride, selenium, silicon, and silicon carbide. Used in diodes, photocells, thermistors, transistors, etc.
