چکیده

Current driven instabilities in the collector of III–V heterojunction bipolar transistors ~HBT! are investigated. Numerical simulations indicate that in a modified AlGaAs/GaAs HBT the collector current shows oscillatory behavior due to the transferred-electron ~Gunn–Hilsum! effect. Influence of the Kirk effect as well as conditions for oscillation are discussed. © 1995 American Institute of Physics.

Novel Transient Phenomena in Heterojunction Bipolar Transistors

The interaction between transferred-electron effect and base widening under transient conditions in III-V heterojunction bipolar transistors is considered. Modification of the collector field profile with an n+ doping spike is shown to cause a time delay for the onset of Kirk effect creating conditions for the inception of charge instabilities. Numerical simulations suggest the possibility of s...

Space-charge recombination currents and their influence on the dc current gain of AlGaAs/GaAs Pnp heterojunction bipolar transistors

The effects of Shockley–Read–Hall, Auger, radiative, and intrinsic surface base recombination processes in the emitter-base space-charge region on the current gain of Pnp AlGaAs/GaAs heterojunction bipolar transistors are analyzed. At low forward emitter-base bias, the current gain of a typical Pnp AlGaAs/GaAs heterojunction bipolar transistor is shown to be reduced substantially below its valu...
