      More Details Abstract Fulltext PDF

      All epitaxial gold-NaCl/NaBr-gold capacitors were fabricated on hot NaCl substrates. The dielectric properties, capacitance and loss have been measured. Severe harmonic distortion in the output current has been observed. Maximum contribution was from third and odd harmonics. The amplitude of harmonics was maximum at frequencies above the loss peak. The phenomenon has been explained on the basis of nonlinear space charge theories.

      More Details Abstract Fulltext PDF

      Amorphous selenium alloy films have been found to exhibit excellent photosensitive properties from 300 to 700 nm. These films constitute the essential part of xerographic photoreceptors. Optical absorption, energy band gap and X-ray structural analysis of Se85 Te15 and Se85 As15 films are reported. The effect of annealing on these parameters has also been indicated.
