摘要

The magnitude and spectral dependence of a photocurrent in a nanoscale heterostructure composed of layers of organic copper phthalocyanine semiconductor and ferroelectric polymer located between two electrodes have been studied. The heterostructure is polarized by voltage pulses applied to the electrodes. Almost a ninefold increase in the photocurrent is obtained as a result of ferroelectric polarization by voltage pulses from +30 to -30 V. It is shown that the increase in the heterostructure photocurrent is related to the stimulated polarization of the ferroelectric layer and, as a consequence, is determined by an increase in the strength of the built-in dc field in the semiconductor layer.
