Huiyun Liu

Prof Huiyun Liu

Huiyun Liu received the PhD in Semiconductor Science from the Institute of Semiconductor, Chinese Academy of Sciences. After receiving his PhD, he joined the EPSRC National Centre for III-V Technologies at University of Sheffield in August 2001. He was responsible for the development of Molecular Beam Epitaxy growth of semiconductor materials for the UK academic and industrial research community. In 2007, he was awarded Royal Society University Research Fellow and started his academic career in the Department of Electronic and Electrical Engineering at UCL, where he is currently a Professor of Semiconductor Photonics. He has co-authored over 300 papers in the area of semiconductor materials and devices. His general interest concentrates on the nanometre-scale engineering of low-dimensional semiconductor structures (such as quantum dots, quantum wires, and quantum wells) by using molecular beam epitaxy and the development of novel optoelectronic devices including lasers, detectors, and modulators by developing novel device process techniques.

Dr. João Valente

João Pedro Mire Dores Pulido Valente received his PhD degree, in 2016, from the Optoelectronics Research Center at the University of Southampton. During his PhD project he developed nanomechanically reconfigurable metamaterials that can be rearranged by application of electric or magnetic triggers. The success of this work was enabled by very advanced nanofabrication skills, namely focused ion beam milling in combination with different metal deposition, etching and optical characterization techniques. Prior to his PhD, João did his MSc degree, in 2010, from University of Aveiro and Technical University of Hamburg Harburg with the aim of an European Masters in Material Science. His graduate studies were conducted at New University of Lisbon and his final thesis - "Transparent Conductive Metal Oxides for Microelectronics" - was done in collaboration with Renato Archer Research Center in Campinas, Brazil. João’s most striking qualities are a very high level of initiative, creativity, multidisciplinarity and excellent nanofabrication skills. He co-authored several high profile publications in fields ranging from material science, optoelectronic devices and metamaterials. His interests concentrate on the development of nanofabrication tools and concepts that could enable optoelectronic, photonic and plasmonic devices for real world applications.
