Research Associate in Advanced Epitaxy for Semiconductor Optoelectroni

Cardiff University - School of Physics & Astronomy

Applications are invited for a postdoctoral research position funded by the Engineering and Physical Sciences Research Council (EPSRC)-funded Future Compound Semiconductor Manufacturing Hub1 and associated with the Institute for Compound Semiconductors2 (ICS) in the School of Physics and Astronomy at Cardiff University. The role will develop advanced epitaxial methods and nanoscale materials for integrated optoelectronic devices in support of Hub projects and partners. The ICS and Hub form part of > £300m investment in a new research and innovation centre, equipped with epitaxy, state-of-the art fabrication and device characterisation facilities. Stimulated by demand for creative and professional prototyping service, the ICS provides an environment to grow academic research and industrial projects.

The envisioned research will develop micro- and nano-structured Metal Organic Vapour Phase Epitaxy (MOVPE) methods for semiconductor devices on the silicon platform. Example projects may include vertical cavity lasers on silicon, infrared devices, quantum dots and nanowires. This work will focus specifically in arsenic (As), antimony (Sb) and phosphorous (P) materials for near-term applications with relevance to industrial collaborators in within UK and EU. However, independent research aligned with the ICS/Hub activity are highly encouraged.

Candidates will have a PhD in Engineering, Physics or closely-related subject focusing on advanced optoelectronic materials and devices with emphasis on the epitaxy. Please note that substantial hands-on expertise specifically in MOVPE of either III-As, III-Sb or III-P compounds is absolutely essential. Epitaxial integration of III-V on Si, lattice-mismatched materials along with patterned or nanoepitaxy are highly desirable. Additional skills associated with materials characterization, fabrication or devices are also desired. You will have a strong research record demonstrated through publications in high quality academic journals; experience participating in research proposals and research/industry-based groups with proven ability to network effectively with academics and outside academia.

Please submit with your completed application and your full CV. We also require a statement of research interests and career goals (2 pages max).

We encourage informal enquiries about the project, which can be made to Professor Diana Huffaker at Further information on the area of research can be found at or For more information about working at Cardiff University contact Glesni Lloyd on
