Suppression of I-V kink in doped channel InAlAs/InGaAs/InPheterojunction field-effect transistor (HFET) using silicon nitridepassivation

Abstract
The impact of silicon nitride (SiN) surface passivation on the kink effect of doped channel InAlAs/InGaAs/InP HFETs has been investigated for the first time. Experiments show that the I-V kinks of these HFETs can be reduced significantly by using SiN surface passivation.
