The Photovoltaic and Photorefractive Effects in Noncentrosymmetric Materials

Part 1 Phenomenological description: introduction the photovoltaic effect and photoelectric phenomena linear and circular photovoltaic effects polarization aspects of the photovoltaic effect in some crystal types glass coefficients spatially oscillating and steady currents photoinduced fields experiment the magnetophotovoltaic effect conversion efficiency limits to the phenomenological description. Part 2 Principles of the microsopic theory: elementary-process asymmetry basic kinetic-theory formulas for a medium lacking a centre of symmetry the photovoltaic effect in impurity-band transitions band-band transitions shift PVE the scope for nondissipative current flow magnetic-field effects hop mechanism mechanisms related to spatial inhomogeneity. Part 3 The photovoltaic effect in particular materials: gallium arsenide gallium phosphide zinc sulfide tellurium quartz sillenites lithium niobate and tantalate potassium niobate barium titanate lead germanate barium-strontium niobate antimony sulfoiodide other materials. Part 4 Nonlinear optical phenomena due to the photovoltaic effect: the photorefractive effect holographic gratings two-beam coupling photoinduced scattering four-wave mixing. Part 5 Anomalous photoinduced fields: strong fields charge-stransport model hot-electron diffusion charge transfer in a light-induced grating. Part 6 Phenomena related to PVE: the photothermal effect relaxation currents even electrical and thermal conductivities absolute negative photoconductivity the surface photovoltaic effect mirror isomer separation.
