- Аннотация: Silver-palladium nanocomposite films are widely used in electronics. They exhibit a photoresponse sensitive to the polarization and direction of wave vector of incident beam. Here we present the results of experimental research of the effect of direct current bias on the pulse shape of the polarization- and wave vector direction-sensitive photocurrent in Ag/Pd nanocomposite films under nanosecond laser excitation at 532 nm. It was established that the direct current bias applied to the film excites an additional component of the photocurrent, independent of the sign of the angle of incidence, the pulse duration of which is much longer than the one of the polarization- and wave vector direction-sensitive photocurrent. It was shown that depending on the sign of the angle of incidence, the direct current bias may decrease or increase the amplitude, pulse duration and fall time of the total photocurrent pulse. The obtained results show the ability to control the polarization- and orientation-sensitive photocurrent in Ag/Pd nanocomposite films using a dc voltage.
