We report in this paper the effect of the reverse bias stress in AlGaN/GaN HEMTs, observing the current trend during the stress and its correlation with the emission intensity. The increase of the breakdown voltage after the stress, with the other parameters variations, can be related with a charge trapping phenomena in the gate-to-drain channel region.

Abstract
We report in this paper the effect of the reverse bias stress in AlGaN/GaN HEMTs, observing the current trend during the stress and its correlation with the emission intensity. The increase of the breakdown voltage after the stress, with the other parameters variations, can be related with a charge trapping phenomena in the gate-to-drain channel region.File in questo prodotto:
