Abstract

In this paper, a two dimensional (2D) device simulation was used to investigate Kink phenomena in InAlAs/InGaAs HEMT's. Impact ionization was taken into account and it is responsible for the kink. It is found that the accumulation of holes in the gate-source overlap region generated by the impact ionization has the channel electron density increase at the bias point where kink appears. At high drain to source voltage, there is a rapid increase in the drain conductance, and it is known as an on-state breakdown.
