Abstract

An AlGaN/GaN HFET incorporating a piezoelectrically enhanced two-layer barrier structure has been fabricated and characterized. The gate leakage current was observed to be suppressed by one order of magnitude, compared to that in a conventional AlGaN/GaN HFET. Breakdown voltages in the piezoelectrically enhanced and conventional HFET structures are approximately 100 V and have positive temperature coefficients.
