Investigations of photoelectric effects occupy an important place in studies of
semiconductors. Recently investigations of photoconductivity and photoelectromotive forces …

In this paper we concentrate on an analysis of the modulated photocurrent (MPC)
experiment applied to samples of amorphous semiconductors built in coplanar geometry …

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

We describe a technique for the determination of the carrier lifetime (τ) and the carrier
mobilities (μ n, μ p) in semiconductors, namely the moving-photocarrier-grating method. This …

The dynamic behaviour of both diffracted beams in a two-wave mixing configuration, and
induced photocurrent are investigated with nanosecond light excitation. The photorefractive …

We analytically solve charge-transport equations for a photorefractive crystal with shallow
and deep traps. We predict that, if shallow traps can accumulate a high density of charge …

PIN photodiodes and bulk photoconductors used as direct demodulators and as heterodyne
mixers of coherent optical radiation are analyzed by taking the Fourier transform of the …

We find that the temporal shape and speed of dark decays of photorefractive gratings
depend on the light intensity used to write the grating. We attribute this to the fact that the …

A model of the electromagnetic radiation generated by the triggering of large-aperture
biased photoconductors with ultrashort pulses is developed. In the far field, the radiated …

The performance of photoconductor is analyzed, via the concept of the steady-state Fermi
level, and shown to be limited by the injection of space charge. Using the gain-bandwidth …
