Causes of negative photoconductivity in liquid organic semiconductors

Soviet Physics Journal Aims and scope

Abstract

The authors analyze the applicability of the explanations of negative photoconductivity in solid semiconductors to liquid binary systems containing diethyl ether and an organic halogen derivative. Experiments confirm the explanation that the carrier concentration is reduced. The existing model is continued for the origin, drift, and recombination of the charge carriers, and it is used to derive equations for the equilibrium state, the conditions for occurrence of photoconductivity (positive or negative), and thermal and optical quenching. The representation of the short-range order and the equations agree qualitatively with previous measurements, which revealed regularities in the photoconductivities of certain liquids.
