A semiconductor structure is provided having: a semiconductor; a gold-free electrically conductive structure in ohmic contact with the semiconductor; and a pair of electrically conductive layers separated by a layer of silicon. The structure includes: a refractory metal layer disposed in contact with the semiconductor; and wherein one of the pair of electrically conductive layers separated by the layer of silicon is the refractory metal layer. A second layer of silicon is disposed on a second one of the pair of pair of electrically conductive layers and including a third electrically conducive layer on the second layer of silicon. In one embodiment, the semiconductor includes a III-V material.
