A New Technique for the Study of Electronic Transport in Insulators

Abstract

To avoid the barrier limitation at the injecting electrode and the effect of imperfections in the insulator, a low‐energy (−3 Å and the effective mobility is ≈10⁻¹¹ cm²/V sec. Both are nearly independent of the incident energy. Pulse measurements indicate larger absorption coefficient values, especially for kinetic energies >2 eV.
