摘要：
We report an electrical characterization of AlGaAs/GaAs heterojunction bipolar transistors over a temperature range of 250 to 400 K in which the emitter edge current contribution to the negative differential output resistance (NDR) effect is determined. A quantitative analysis of the dc gain versus temperature and perimeter to area ratio indicates that emitter edge has a major influence on the NDR magnitude.
