Abstract

This work investigates temperature-dependent device characteristics of AlGaN/GaN high electron mobility transistors (HEMTs) grown by a metal-organic chemical vapor deposition (MOCVD) system, and passivated by using hydrogen peroxide (H₂O₂) oxidation method. The present oxide-passivated AlGaN/GaN HEMT can effectively improve device performances, including current drive, transconductance, gate-drain forward turn-on voltage (V_on), and gate-drain reverse breakdown voltage (BV_GD) at 300-480 K. In addition, improved RF and power performances have also been achieved as compared with an unpassivated device. The present oxide-passivated AlGaN/GaN HEMT is promising for high-temperature and high-power monolithic microwave integrated circuit (MMIC) applications.
