Jy. Chi et K. Lu, A MECHANISM FOR HYDROGEN-RELATED TRANSIENT EFFECTS IN CARBON-DOPED ALGAAS GAAS HETEROSTRUCTURE BIPOLAR-TRANSISTORS/, IEEE electron device letters, 19(11), 1998, pp. 408-410
The transient phenomenon in carbon-doped AlGaAs/GaAs ABT's has been fo
und to reoccur after a brief thermal annealing under no bias. The temp
erature and the current dependencies have been studied,vith HBT's made
with MOCVD grown wafers. The experimental data can he explained by a
model based on thermal decomposition of C-H complexes during annealing
and electron captures by hydrogen ions under minority-carrier injecti
on.
