摘要
This paper describes DC characteristics of AlGaN/GaN high electron mobility transistors (HEMTs) fabricated on a free-standing GaN substrate. The three terminal breakdown voltage of the fabricated HEMT with a gate length of 3 mu m exhibited a linear increase with increasing the gate-to-drain distance (L-gd), reaching more than 1200 V at L-gd=25 mu m. It was found that the ON/OFF ratio in the drain current was only 10(4), indicating the need for further improvements in buffer structure design.
