Photoinduced Schottky barrier in photorefractive materials.
We report on the first experimental evidence of a Schottky barrier effect produced by the action of light in an otherwise purely Ohmic contact between a nominally undoped photorefractive titanosillenite Bi12TiO20 crystal and a transparent conductive SnO2 electrode. The photorefractive crystal is sandwiched between two transparent electrodes and a Schottky barrier is built up in the illuminated ...
متن کاملTunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
متن کاملDevelopment of Diamond Schottky Barrier Diode
Diamond, which has excellent physical properties, is attractive for use in industrial applications. Because diamond is rated the highest for hardness and heat conductivity among all known materials, it is widely used for products such as abrasive grains, cutting tools, and heatsinks. Diamond also exhibits excellent transparency even in the ultraviolet range and can be applied to optical tools. ...
متن کاملTemporal evolution of fanning in photorefractive materials.
We present detailed calculations of the temporal and spatial evolution of beam fanning in photorefractive crystals that is initiated by scattering from noise. We show that fanning starts from beam coupling between the incident radiation and part of the incident radiation scattered by noise at or near the input plane. We show that scattering within the volume of the crystal has negligible effect...
