title = "Reduction in lags and current collapse in field-plate AlGaN/GaN HEMTs with high acceptor density in a buffer layer",

abstract = "We make a two-dimensional transient analysis of fieldplate AlGaN/GaN HEMTs with a semi-insulating buffer layer, where a deep acceptor above the midgap is considered. It is studied how the deep-acceptor density NDA and the field plate affect buffer-related lag phenomena and current collapse. NDA is varied between 1017 cm-3 and 8×1017 cm-3. It is shown that without a field plate the drain lag and current collapse increase with increasing NDA as expected, although the gate lag decreases when NDA becomes higher than 2×1017 cm-3. But with a field plate, surprisingly, the lags and current collapse decrease when NDA becomes high. This is attributed to the fact that the reduction in drain lag and current collapse by introducing a field plate becomes more significant when NDA becomes higher.",
