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.
