Organic Resonant Tunnelling Diodes

Wallace C. H. Choy received his PhD Degree in Electronic Engineering from the University of Surrey, UK. He then joined National Research Council of Canada as a member of research staff to work on optical device structures of polarization independent optical amplifiers and modulators. He joined with Fujitsu at San Jose, US in 2001 to develop real-time wavelength tunable lasers and optical transmitter modules. He is now an Assistant Professor of Department of Electrical and Electronic Engineering, the University of Hong Kong (HKU). His current research interests are concerned with organic optoelectronic devices and nano-material devices. Dr. Choy has published over 75 internationally technical journal papers, contributed to two book chapters, US and China patents. He received Outstanding Achievement Award from National Research Council of Canada in 2001 and overseas visiting fellowships from HKU to take a sabbatical in George Malliaras's Group, Cornell University in 2008,visit Prof. Y. Yang, UCLA in the summer of 2009 and visit Prof. Karl Leo, IAPP, Dresden, Germany in the summer of 2010.

The Department of Electrical and Electronic Engineering was established at the University of Hong Kong in 1961. Over the last few decades, our graduates have been serving the society in key positions and have made tremendous impact to the development of Hong Kong in its evolution from an industrial-based to knowledge-based economy. A characteristic of our Department is that we cover electrical, electronic, computer and information engineering all under one roof, which provides tremendous opportunities for cross interaction both in terms of teaching and research. The Department has a wide range of research activities, grouped under seven areas, namely (i) Computer Systems and Networking, (ii) Telecommunications, (iii) Microelectronics, Optoelectronics and VLSI, (iv) Electrical Energy Technologies & Systems, (v) Biomedical Engineering, (vi) Information Systems, and (vii) Electromagnetics and Optics. Our research activities are supported by more than 100 research grants awarded over the last three years. Apart from basic research, our staff have been actively engaged in applied research and technology transfer.
