Guo, Dengzhu is an associate research fellow in the Department of Electronics, School of EECS. He obtained his B.Sc. from Northwest Normal University in 1990, M.Sc. from Chinese Academy of Space Technology in 1993, and Ph.D. from Peking University in 2003, respectively. His research interests include synthesis and applications of nanostructured materials. 

Dr. Guo has published more than 50 research papers in conferences and journals, including high impact journals such as JACS, JPCB, Chem. Commun., and Appl. Surf. Sci. He is also an inventor of several patents. He is an expert in nanomaterials synthesis, vacuum technology and vacuum nanoelectronics. His main interests are applying nanomaterials in filed emission electron sources, in optoelectronic devices, and in sustainable energy devices.

Dr. Guo has been responsible for more than ten research projects including NSFC, 863 project, and technical development items from industries. His research achievements are summarized as follows:

1) He proposed a new structure of field emission electron sources, providing a feasible solution of a long-term world challenge: how to fabricate a practical emission electron source with high stability and long lifetime. He has successfully used this invention in portable time-of-flight mass spectrometers.

2) He invented a micro-vacuum camber sealing technique based on MEMS technology, which has been used by other researchers in the development of micro-atomic clocks and micro-magnetometers.

3) He invented a route to synthesis black TiO2 nanoparticles, which has excellent wide-spectral optical absorption and nonlinear optical properties. He is doing the researches in applying such materials in energetic and optoelectronic devices.
