This review volume is based primarily on the balance equation approach developed since 1984. It provides a simple and analytical description about hot electron transport, particularly, in semiconductors with higher carrier density where the carrier-carrier collision is much stronger than the single particle scattering. The steady state and time-dependent hot electron transport, thermal noise, hot phonon effect, the memory effect, and other related subjects of charge carriers under strong electric fields are reviewed. The application of Zubarev''s nonequilibrium statistical operator to hot electron transport and its equivalence to the balance equation method are also presented. For semiconductors with very low carrier density, the problem can be regarded as a single carrier transport which will be treated non-perturbatively by the nonequilibrium Green''s function technique and the path integral theory. The last part of this book consists of a chapter on the dynamic conductivity and the shot noise suppression of a double-carrier resonant tunneling system.

Dr W Kroll, a young post-doc working under Heisenberg at Leipzing in the 1930s, was forced to escape from the Nazis and eventually came to the National Taiwan University in 1941. He taught many of the advanced courses in theoretical physics for over two decades, and prepared a generation of physicists in Taiwan. A symposium on pure and applied physics was held in memory of Prof Kroll at the University of Massachusetts Dartmouth in August 1996. These proceedings, composed of papers contributed to the symposium by many of Prof Kroll''s former students now reaching professorial ranks in the West, reflect in a small measure the legacy he left behind.
