Sun, Lei is an associate professor in the Department of Microelectronics, School of EECS. He obtained his B. Sc., M. Sc. and Ph. D. from Peking University in 1997, 2000 and 2003 respectively. His research interests include semiconductor device physics, emerging device design and fabrication, organic device and circuit design.

Dr. Sun has published more than 50 research papers, and most of them are published in international journals and conferences, such as Jpn. J. Appl. Phys., IEEE Trans. Electron Devices, J. Display Tech. He has owned more than ten China patents. He joined Beijing science and technology nova project in 2006, and received Beijing science and technology award in 2007, serving as the member of the winning team.

Dr. Sun has been in charge of six research projects including NSFC, BJNSF project, etc. His research achievements are summarized as follows:

1)  Design and fabrication of emerging transistors: Nanowire transistors have been considered as the most outstanding solutions to continue Moore’s Law, because of their excellent gate control. Dr. Sun focused on the research of the optimization technologies for nanowire transistors. He has studied on germanium based gate-all-around structures for high performance requirement, tunneling nanowire transistors for steep-slope requirement, and triangle/diamond shaped cross-section nanowire transistors for low temperature fabrication of devices.

2)  Modeling and simulation of device physics: Device simulation is always the feasible way to study the working mechanism of the devices and is helpful for the design of the device structure and parameters. Dr. Sun focused on the Schottky barrier modeling and the simulations of the corresponding devices, including dopant-segregated Schottky source/drain transistors, asymmetric Schottky source/drain transistors, and dual barrier transistors. He also proposed the direct tunneling model of Schottky barrier with full band Monte Carlo simulation.

3)  Organic transistors design and fabrication: Organic transistors have received much attention for the potential application on the modern display technology and internet of thing requirements. Organic transistors can be fabricated feasibly and applied for the low temperature procedures. Dr. Sun focused on the characterization of organic transistors, such as double gate organic TFTs and stacked channel organic TFTs. He is also interested in the design of driver circuit for OLED display technology with organic transistors.
