Relaxation of Impurity-Defect Complexes in Fluorite Crystalsn alkaline earth fluroides. For the most part the relevant investigations involve relaxation of electric polarization as revealed by the ionic thermo-current (ITC) method on CaF., SrF. and BaF. crystals doped with a variety of trivalent rare earth (RE.) ions. In the absence of contaminating oxygen t

The Capture of Electrons by Negatively Charged Impurity Atoms in N-Type Germanium the way in which the electron loses energy in its transition from the conduction band to a captured state. We have studied the dependence of capture rate on the external electric field at law temperature (20°K) for n-Ge containing gold centres as impurities.

Radiation Defects in Heavily Irradiated GaAsmens of n- and p-type GaAs are characterized by very low conductivity, carrier density and Hall mobility and large optical absorption in the interval of 0.5–1.5 eV. With increasing dose, the hole mobility, in contrast to electron mobility, decreases initially and passes through a minimum that is cau

Electrical Switching in Calcium Phosphate Glasses Containing Iron glasses. The switching phenomena was studied using a.c. and d.c. voltages. The samples showed switching, from a high resistance state (off-state ≥ 10 M Ω) to a low resistance state (onstate ≤ 1 KΩ) at certain threshold voltages. The switching was invariably of the memory type and a high current pul

Role of Iron and Electrical Conductivity in Iron Calcium Phosphate Glassesre and after heat treatment. Factors affecting the electrical conductivity of these glasses included the total iron concentration, ferrous-ferric ratio, devitrification by heat treatment, and the type of local order in the glass. An exponential decrease in log ρ was observed with increasing total ir

Properties of Simultaneously Sputtered Thin Metal Filmshodic sputtering method. Bimetal or multimetal films were sputtered simultaneously, using a specially designed multilayer cathode. The effect of sputtered carbon on the properties of the single or multimetal films was tested using an additional cathode. Techniques included visual examination of colo

Indirect Exciton with Degenerate Valence Band in the Two-Photon Absorption in Semiconductorswhen the valence band is degenerate in semi-conductors. A group theoretical analysis is performed for the case of GaP (or III – V compounds) in order to determine which transition is allowed in the process, the symmetry of the excitons, and the symmetry of the phonons which contriubte in the transit
