Photoinduced charge dynamics in photorefractive semiconductors is studied from both,
theoretical and experimental points of view in the case of an external field screening. This …

It is shown that in materials with a special type of photoconductivity temporal response, the
running space charge wave is generated under uniform illumination when the external …

The transient behavior of the fundamental amplitude of the photorefractive space-charge
field is derived without restrictions within the band transport model. The two-wave mixing …

The excitation of a space charge wave in a uniformly illuminated photorefractive crystal by
an applied ac voltage is studied theoretically. A spatial differential equation for the ac …

We have measured the real and imaginary parts of the experimental rate constant of the
buildup and decay of photorefractive charge gratings in cubic crystalline insulating Bi 12 SiO …

A model of the photorefractive effect is presented that includes a shallow-trap level (hole or
electron trap) as well as a species of deep traps with electron and hole excitation. It is shown …

It is shown that weakly damped space-charge waves exist in photorefractive crystals with a
sufficiently large lifetime–mobility product. The dispersion law, the damping constant, and …

Recent analytical results in the frame of photorefractive spatial-soliton propagation are
exploited to derive a novel scheme for the investigation of space-charge field formation in …

A microscopic model of the non-steady-state photoelectromotive force excited by a vibrating
interference pattern in a bipolar photoconductor under an external dc electric field is …

We show that a photoconductive crystal, placed in a rapidly alternating ac field and exposed
to nonuniform light, exhibits singularities of the induced space charge and discontinuities of …
