    摘要: A method for fabricating a single crystal, high quality, semi-insulating (SI) gallium nitride (GaN) layer using an AlxGa1-xN blocking layer. A buffer layer is grown on a substrate, the AlxGa1-xN blocking layer is grown on the buffer layer, and a single crystal, high quality, SI-GaN layer is grown on the AlxGa1-xN blocking layer. The AlxGa1-xN blocking layer acts as a diffusion blocking layer that prevents the diffusion of donors from the substrate from reaching the SI-GaN layer. The resulting SI-GaN layer reduces parasitic current flow and parasitic capacitive effects in electronic devices.

    摘要: A III-nitride photovoltaic device structure and method for fabricating the III-nitride photovoltaic device that increases the light collection efficiency of the III-nitride photovoltaic device. The III-nitride photovoltaic device includes one or more III-nitride device layers, and the III-nitride photovoltaic device functions by collecting light that is incident on the back-side of the III-nitride device layers. The III-nitride device layers are grown on a substrate, wherein the III-nitride device layers are exposed when the substrate is removed and the exposed III-nitride device layers are then intentionally roughened to enhance their light collection efficiency. The collection of the incident light via the back-side of the device simplifies the fabrication of the multiple junctions in the device. The III-nitride photovoltaic device may include grid-like contacts, transparent or semi-transparent contacts, or reflective contacts.
