Recent advances in high-speed photoconductors have led to devices which have
subpicosecond response times.\In addition to their application as detectors, these devices …

The surface photoelectric current from a pure metal surface is calculated when the frequency
of the incident radiation is less than the threshold frequency but greater than one-half the …

An interrupted field time‐of‐flight (IFTOF) technique that enables displacement‐current‐free
measurement of the photocurrent in the conventional transient photoconductivity experiment …

Solutions are obtained for the refractive index grating in a photorefractive material in which
the writing or erasing beams are short-pulse (less than tens of nanoseconds), high …

The application of photoconductors to fast rise time, high‐power switching is discussed. We
report the successful switching of a 100‐kV system to generate a 1.8‐kA,< 5‐ns rise time …

This review presents the fundamental theoretical concepts concerning the photogalvanic
effect (PGE)—the phenomenon of appearance of a direct current in a homogeneous …

A simple model is studied describing low-temperature free-carrier dynamics in extrinsic
photoconductors due to capture by impurity atoms and impact ionization. Numerical results …

Beam coupling effects in an optically active photorefractive crystal of Bi 12 SiO 20 are very
much influenced by the polarization direction of the interacting beams. Analytic expressions …
