Abstract: A method for fabricating a photovoltaic device includes applying a diblock copolymer layer on a substrate and removing a first polymer material from the diblock copolymer layer to form a plurality of distributed pores. A pattern forming layer is deposited on a remaining surface of the diblock copolymer layer and in the pores in contact with the substrate. The diblock copolymer layer is lifted off and portions of the pattern forming layer are left in contact with the substrate. The substrate is etched using the pattern forming layer to protect portions of the substrate to form pillars in the substrate such that the pillars provide a radiation absorbing structure in the photovoltaic device.

Abstract: An electronic device includes a spreading layer and a first contact layer formed over and contacting the spreading layer. The first contact layer is formed from a thermally conductive crystalline material having a thermal conductivity greater than or equal to that of an active layer material. An active layer includes one or more III-nitride layers. A second contact layer is formed over the active layer, wherein the active layer is disposed vertically between the first and second contact layers to form a vertical thin film stack.
