The effect of the non-steady-state photoelectromotive force in 6H-SiC crystals irradiated by reactor neutrons has been investigated experimentally. The dependences of the signal amplitude on the phase modulation frequency, spatial frequency, light in

The non-steady-state photoelectromotive force effect was experimentally studied in a semiconductor nanowire array, i.e., in a composite representing selenium in a chrysotile asbestos matrix. The sample was exposed to an oscillating interference patte

The emergence of optical waves out of optical noise (fanning) in a photorefractive medium is considered in an unconventional manner, i.e., using the Lorentz lemma and ensemble averaging. The derivation of equations for four-wave interaction in the sc

Bi12SiO20 and Bi12TiO20 crystals doped with l0-5 to 2 x 10-2 wt % Cr were grown by the Czochralski technique. The Cr content of the crystals and the valence state of Cr ions were determined by a new analytical technique with the use of 1,5-diphenylca

Averaged equations are derived describing the process of relaxation of reversed waves in the case of complex light fields in a scheme of double reversing mirror. Qualitative agreement between the experimentally derived and calculated time dependences

Crystals with the sillenite structure, grown in an oxygen-free (argon) atmosphere, are investigated by the ac photovoltage method. It is found that the photoconductivity in red light is sharply higher (by two orders of magnitude) than in crystals gro

The parameters of Bi12TiO20 crystals grown with bismuth oxide of different degrees of purity were measured by a holographic recording technique in an external ac electric field and were compared with a crystal specially doped with chromium. Various c

We report the excitation of nonstationary holographic currents in semi-insulating 6H-SiC crystal preliminarily irradiated by reactor neutrons. The currents are studied for the cases of zero and non-zero external electric fields. The dependences of th

It is shown that the two-wave amplification in an alternating field in photorefractive crystals of the sillenite family is strongly affected by the drift length of photoinduced charge carriers. Consequently in samples with short drift lengths the two
