Unipolar charge sensing with coplanar electrodes-application to semiconductor detectors

Charge transport in arrays of semiconductor gamma-ray detectors.

We analyze the effects of electrode size on performance of arrays of semiconductor gamma-ray detectors, especially when there is significant charge trapping. With large electrodes, motions of holes and electrons are of equal importance, but when the positive electrode is segmented into an array of small elements the contributions of holes to the output, and hence the effects of hole trapping, a...

Interfacial charge-transfer absorption: 3. Application to semiconductor-molecule assemblies.

Interfacial charge-transfer absorption (IFCTA) provides information concerning the barriers to charge transfer between molecules and the energy levels of a metal/semiconductor and the magnitude of the electronic coupling and could thus provide a powerful tool for understanding interfacial charge-transfer kinetics. Here we utilize a previously published model (J. Phys. Chem. B 2005, 109, 10251) ...

Semiconductor Electrodes

Irradiated suspensions of sem~ single crystal and polycrystalline conductor powders, e.g., Ti02, have semiconductor materials currently been employed in such heterogeneous being investigated. Measurements photo processes as the oxidation of involving such slurry electrodes cyanide, the decomposition of carare of use not only for the charboxylic acids, and the deposition acterization of the powd...

Terahertz sources and detectors and their application to biological sensing.

Terahertz spectroscopy has long been used as an important measurement tool in fields such as radio astronomy, physical chemistry, atmospheric studies and plasma research. More recently terahertz technology has been used to develop an exciting new technique to investigate the properties of a wide range of biological materials. Although much research remains before a full understanding of the int...
