Abstract
Conductivity modulation was observed in thin films of chalcogenide glass by applying an electric field through the (mica or plastic) substrate. At room temperature, the surface potential could be varied through ± 3kT, the surface being always p type, in agreement with the Seebeck coefficient. Comparison of the field‐effect curves with equilibrium space‐charge theory suggests a bulk density of localized states in the range from 1019 to 2 × 1020 cm−3 eV−1 within ± 0.1 eV of the Fermi level.Keywords
