摘要
An AlN Layer grown by an ALE has been developed to improve the growth quality of GaN on Al 2O 3 substrate by low pressure metalorganic vapor phase epitaxy (LP MOVPE). An ALE AlN layer grown on Al 2O 3 substrate has a high quality and the structure is similar to GaN, this AlN layer can release the stress between Al 2O 3 substrate and GaN epilayer. By using this method, the orientation of substrate is extended to GaN epilayer, and the column tilt and the twist are improved, so as to obtain the device quality GaN.
