Abstract

Hot electron trapping can significantly modify the performance of GaN-based HEMTs during hard switching operation. In this letter, we present a physics-based model based on rate equations to model the trapping kinetics of hot-electrons in GaN transistors submitted to semi- ON-state stress. The model is validated through comparison with the experimental data, obtained by means of a pulsed-drain current transient setup developed ad-hoc. Hot-electron trapping is found to have logarithmic time dependence; the first 10 μs of operation are critical in determining the current collapse during stress.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
