Wafer Scale Cryostat

The EPSRC National Epitaxy Facility (NEF) at the University of Sheffield supplies a wide range of III-V semiconductor materials and devices primarily to the UK academic research community. The NEF also engages in significant activity researching and developing new materials and structures. Many of the materials produced by the NEF are intended for photonic and optoelectronic applications that often require photoluminescence based characterisation to determine material quality and compliance with design specificatio...
