UCL MBE Research group is led by Prof Huiyun Liu, who joined UCL in 2007. As part of the Photonics Group at Department of Electronic and Electrical Engineering, MBE group focuses on semiconductor photonic and optoelectronic devices and materials. We have professional staff working on MBE epitaxial growth, device fabrication and measurement. In January 2010, MBE laboratory was opened by HRH the Princess Royal. Until now, we have been working on a wide range of nano materials and devices, including III-V quantum dot lasers and solar cells, III-V nanowire, multijunction solar and thermophotovoltaic cells.
