Abstract

Al 0.26Ga 0.74N/AlN/GaN heterostructures with a 1-nm-thick AlN interfacial layer were grown on 100-mm-diameter epitaxial AIN/sapphire templates by metalorganic vapor phase epitaxy. They exhibited very high Hall mobilities of approximately 2100 cm 2/Vs at room temperature and approximately 25000 cm 2/Vs at 15 K with a sheet carrier density of approximately 1 × 10 13/cm 2. High-electron- mobility transistors were successfully fabricated on the epitaxial wafers. The device exhibited a high drain current density of 832 mA/mm and high extrinsic transconductance of 189 mS/mm.
