摘要
We experimentally measure a departure from conventional scaling of current gain-beta with base thickness x(B) in abrupt junction n-p-n heterojunction bipolar transistors. It is empirically established that extreme nonequilibrium electron transport in the base causes beta to vary as approximately 1/x(B). In our AlInAs/InGaAs transistors this new behavior occurs for base thickness x(B) less-than-or-similar-to 1000 angstrom.
