Abstract(in English) $Al_{0.85}Ga_{0.15}N$/$Al_{0.60}Ga_{0.40}N$ HEMT structures with channel thicknesses of 100?1000 nm were grown on low-dislocation-density AlN templates prepared by a combination of sputtering and high-temperature annealing using the MOVPE method, and the effect of channel thickness on HEMT properties was investigated. Both the surface flatness and crystallinity of the HEMT structure decreased with increasing channel thickness, while the sheet carrier concentration and Hall mobility increased with increasing channel thickness up to 500 nm, and then began to decrease. The I-V characteristics of HEMT with a channel thickness of 500 nm indicated a saturation current density of 7.6 mA/mm, and the off-state characteristics exhibited a breakdown voltage of 1 kV with drain-source length of 20 $mu$m.
