III-V Technologies

The semiconductor growth services located at Sheffield and Cambridge form the III-V semiconductor capability of the EPSRC National Epitaxy Facility. Together, Sheffield and Cambridge can supply all the important III-V materials combinations with bandgaps ranging from the ultraviolet to the mid-infrared. Grown by either molecular beam epitaxy or metal-organic chemical vapour deposition.
