    摘要: Hydride phase vapor epitaxy (HVPE) growth apparatus, methods and materials and structures grown thereby. A HVPE growth apparatus includes generation, accumulation and growth zones. A first reactive gas reacts with an indium source inside the generation zone to produce a first gas product having an indium-containing compound. The first gas product is transported to the accumulation zone where it cools and condenses into a source material having an indium-containing compound. The source material is collected in the accumulation zone and evaporated. Vapor or gas resulting from evaporation of the source material forms reacts with a second reactive gas in the growth zone for growth of ternary and quaternary materials including indium gallium nitride, indium aluminum nitride, and indium gallium aluminum nitride.

    摘要: A method of growing planar non-polar m-plane III-Nitride material, such as an m-plane gallium nitride (GaN) epitaxial layer, wherein the III-Nitride material is grown on a suitable substrate, such as an m-plane Sapphire substrate, using hydride vapor phase epitaxy (HVPE). The method includes in-situ pretreatment of the substrate at elevated temperatures in the ambient of ammonia and argon, growing an intermediate layer such as an aluminum nitride (AlN) or aluminum-gallium nitride (AlGaN) on the annealed substrate, and growing the non-polar m-plane III-Nitride epitaxial layer on the intermediate layer using HVPE. Various alternative methods are disclosed.
