Recombination activity of contaminated dislocations in silicon: a model describing electron-beam-induced current contrast behavior
(The American Physical Society, 2001)
Existing experimental data give many evidences that the recombination rate of minority charge carriers at dislocations in silicon depends strongly on dislocation decoration by transition metal impurities. Here, we present ...
Silica gel from rice hull ash: preparation and characterization
(American Association of Cereal Chemists, Inc., 1998-07)
Rice hulls, a waste coproduct of the rice industry, is composed of 20% silica. The objectives of this study were to develop a method to recover silica from rice hull ash and produce silica gel, and to determine the physical ...
