Two-dimensional transient analysis of field-plate AlGaN/GaN HEMTs is performed in which a deep donor and a deep acceptor are considered in a semi-insulating buffer layer. It is shown that drain lag is reduced by introducing a field plate, because the buffer-trapping effects are reduced. It is also shown that buffer-related lag phenomena and current collapse are also reduced in the field-plate structure.
