  • Abstract
    Nitride-based Al0.24Ga0.76N/GaN heterostructure field effect transistors (HFETs) with carrier confinement layers were fabricated. The results found that the enhanced 2 dimensional electron gas (2DEG) carrier mobility from 1070 to 1180 cm2V-1sec-1 by the insertion of a Mg-doped semi-insulating carrier confinement layer with a Cp2Mg flow rate of 2.36×10-8 mole/min and smoother sample surface. The DC and RF characteristics of these HFETs were also good.
