About Us

We provide collaborative access to world class expertise and facilities, enabling top-rate scientific research in physical, engineering and biomedical sciences through III-V and Silicon technologies.

  Welcome to the National Epitaxy Facility

  • The Facility is a consortium between the Universities of Sheffield, Cambridge and University College London and is funded by the Engineering and Physical Sciences Research Council as part of a network of National Research Centres.
  • Our mission is to provide a range of high-quality bespoke epitaxial wafers and devices that underpin world-class semiconductor research to UK academics and industrial customers, and to support the impact of this research in the scientific and industrial strategy of the Nation.
  • The University of Sheffield has been providing such a service to the semiconductor research community since 1979.
  • We provide a full range of group III-V semiconductors and Si/Ge-based group IV materials by both the MBE and MOVPE techniques. Based on these materials, and working with our extensive network of users, we also produce a broad range of novel devices including LEDs, lasers, quantum circuits, transistors, advanced detectors and solar cells.
