Abstract :
We performed channel hot carrier stress on enhancement-mode, inversion-type III-V MOSFETs with Al2O3 gate dielectric. The stress induces subthreshold swing degradation, increase on the threshold voltage and reduction of drain saturation current. Nonetheless, no appreciable transconductance degradation can be observed at least with a stress time as long as 105 s.
