… in photorefractive media is derived for a simple two-level electron–hole-transport model.
At one level, charge transfer occurs by electron transport, and at the other, by hole transport, …

… 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 …

… hole transport in the photorefractive composite occurs through the network of chromophores
and not through the charge-transport … For hole transport media the charge-generation layer …

… The nonlinear response of the photorefractive medium is stronger for smaller values of
the applied field, a result similar to the Kukhtarev [9] and shallow trap models [18]. …

… Photorefractive crystals are an excellent recording medium … the capabilities of photorefractive
crystals [21–28]. The … simultaneous electron-hole transport in photorefractive materials [93]. …

… crystals compared with other holographic storage media, eg, photoplates or thermoplastics.
However, reconstruction requires illumination of the crystal which erases the stored …

We report on photoelectric and holographic investigations of an organic photorefractive
material based on a low molar mass glass with both photoconductive and nonlinear optical …

… large values for the preparation of efficient photorefractive composite. Since the
chromophores are rotating within an amorphous medium, they typically exhibit a nonexponential …

… We determine the corresponding rates for hole transport by exchanging the index e with the
index h in … We obtain similar expressions for hole transport by conjugating the corresponding …

… "pump" waves in a homogeneous, transparent, nonlinear medium. These beams interact in
the volume of the photorefractive material to produce a fourth wave complex conjugate to the …
