These hybrid devices use the proximity effect to potentially be more efficient than either of the materials alone. In order to make these devices, we first grew high quality samples of tungsten silicide and characterized them before growing hybrid films useful for nanoscale devices. We tested a hybrid chip with a number of nanowire devices expecting more efficient and faster detectors than the material alone.
