Carrier multiplication is the process in which the absorption of a single, high-energy photon results in the generation of two or more electron–hole pairs. The excess energy of the initially excited ...

Computer scientists have discovered a new way to multiply large matrices faster than ever before by eliminating a previously unknown inefficiency, reports Quanta Magazine. This could eventually ...

IF electrons move through a gas in an electric field, their number can increase if they ionize gas molecules by collision—the well-known Townsend avalanche. Recently, it has been shown 1 that in ...
