Abstract
Two-dimensional transient simulation of a GaN MESFET is performed in which deep levels in a semiinsulating buffer layer is considered. It is shown that the drain voltage VD is raised, the drain current overshoot the steady-state value, and when VD is lowered, the drain current remains at a low value for some periods, showing drain lag behavior. This drain lag is shown to become a cause of so-called power compression in the GaN MESFET.
