Abstract:
1. A method for fabricating Group-III nitride, comprising: growing one or more non-polar Group-III nitride layers on a surface of a substrate using vapor phase epitaxy, including; (a) transporting a Group III-source to the surface of the substrate using one or more carrier gates, wherein the Group III source reacts with a nitrogen precursor at a surface of the substrate to grow the non-polar Group-III nitride layers, (b) selecting one or more growth pressures, the one or more carrier gases, one or more growth temperatures, and one or more gas velocities, wherein; the non-polar Group-III nitride layers have a grown top surface that is planar and a non-polar plane, with a root mean square roughness, as grown, below 0.8 nanometers over a sampling area of at least 2 by 2 micrometers, and the non-polar Group III-nitride layers comprise a laser diode, light emitting diode, or transistor structure.
