摘要：

The paper reports on plasma-assisted MBE growth of good quality N-face GaN layers directly on c-Al2O3 substrates. Growth kinetics under different growth conditions (substrate temperature, Ga to activated nitrogen flux ratio, etc.) during deposition of GaN(0001) and GaN(000 (1) over bar) both by the ammonia-based MBE or plasma-assisted MBE was studied. It was found that atomically smooth surface of 1 mu m thick GaN(000 (1) over bar) films can be achieved by plasma-assisted MBE at the relatively high substrate temperature is T-s approximate to 760 degrees C and Ga to activated nitrogen flux ratio F-Ga/F-N* approximate to 1.8.
