Abstract :
The transient phenomenon in carbon-doped AlGaAs/GaAs HBT´s has been found to reoccur after a brief thermal annealing under no bias. The temperature and the current dependencies have been studied with HBT´s made with MOCVD grown wafers. The experimental data ran be explained by a model based on thermal decomposition of C-H complexes during annealing and electron captures by hydrogen ions under minority-carrier injection.
