  • VICINAL SEMIPOLAR III-NITRIDE SUBSTRATES TO COMPENSATE TILT OF RELAXED HETERO-EPITAXIAL LAYERS
    Publication number: 20120100650
    Abstract: A method for fabricating a semi-polar III-nitride substrate for semi-polar III-nitride device layers, comprising providing a vicinal surface of the III-nitride substrate, so that growth of relaxed heteroepitaxial III-nitride device layers on the vicinal surface compensates for epilayer tilt of the III-nitride device layers caused by one or more misfit dislocations at one or more heterointerfaces between the device layers.
