摘要
GaAlN/GaN superlattices are grown onto GaN by MOCVD. Cross sectional transmission electron microscopy is used for the characterisation of the layers. V-shaped surface pits are observed on the surface of the layers. Inversion domains are found consequently in the middle of the V pits. Segregation of aluminium occurs in the inverted hexagonal pyramids.
