A photorefractive effect which results from the spatial separation of electrons and holes in
compositionally graded semiconductors is demonstrated for the first time. Unlike …

For most regimes descriptions of photorefractive behavior by electron–hole transport with a
single species of impurity levels and by electron–hole transport with two species of impurity …

Principal and complementary space-charge gratings are formed in photorefractive bismuth
silicon oxide with use of 785-nm light. An electric field is optionally applied in the direction of …

Dynamics of space-charge field formation and its decay, as well as those of photoexcited
electrons and holes, by picosecond two-beam excitation in photorefractive semiconductors …

Space-charge grating formation and the non-steady-state photoelectromotive force
(photoEMF) excited by a vibrating interference pattern are analyzed for the general case of a …

The coherent oscillation, because of nearly degenerate four-wave mixing in photorefractive
crystals with two types of movable charge carriers, occurs at two spectral lines symmetrically …

It is shown that the spatial variations of physical quantities like space charge electric field,
ionized donor density modulation and electron density modulation may be characterized by …

The response of photorefractive materials to sinusoidal intensity patterns of high modulation
depths is considered. It is shown that the induced refractive-index response in this regime is …

Hot-electron transport in photorefractive semiconductors strongly affects the recording of
photorefractive grating. However, the theoretical description of this behavior has been …

The transients in photorefractive two-wave mixing are investigated under the condition when
the electron generation time is comparable with the dielectric relaxation time. It is shown that …
