August, 2013	If an n-type ZnO is combined with a p-type Si, what do we get? It is not just a p-n heterojunction diode, it is also a self-rectifying nonvolatile memory. We discovered this and published the results on Scientific Reports (view pdf of this paper), a new journal in Nature Publishing Group. Check how a few media outlets say about this technology: IEEE Spectrum: http://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/nanoislands-simplify-structure-of-resistive-memory-devices Phys.org: http://phys.org/news/2013-08-advancing-resistive-memory-portable-electronics.html
November, 2012	Sheng Chu has joined the School of Physics and Engineering at the Sun Yat-sen University, Guangzhou, China as a Full Professor.

June, 2012	Best Student Paper Award is given to a paper titled “Nano Crystal Quantum Dots Tunable On-Chip ESD Protection”, which was presented at the IEEE Radio-Frequency Integrated Circuit Symposium (RFIC) held in Montreal, Canada. This paper is a result from the collaborated effort between Prof. Albert Wang’s group and our group. QSL student Bei Li fabricated and characterized electrical properties of nanocrystal memories. Zitao Shi and other students in Prof. Wang’s group carried out electrostatic discharge (ESD) studies of the devices. Zitao presented the paper in this conference, which is a premier venue for researchers around the world to report the latest results in the area of high-frequency IC technologies and designs.
July, 2011	Sheng Chu, Guoping Wang, et al published results on electrically pumped zinc oxide nanowire waveguide lasers on Nature Nanotechnology (view pdf of this paper). Nature Nanotechnology is the highest impacted scientific journal in Nanoscience and Nanotechnology (impact factor is 30.3 in 2010). In this paper, we demonstrated that ZnO nanowires can emit ultraviolet waveguide lasing in an electrically pumped way for the first time, adding new knowledge in the ZnO nanowire laser field where traditionally only optical pumping generated waveguide lasing (read Prof. Peidong Yang’s group of UC Berkeley’s paper on optically pumped ZnO nanowire laser published in the journal Science in 2001, which has been cited about five thousand times as of this month, indicative of the impact of nanowire laser). There have been tremendous interests from both scientific community and general public on this latest development. More than one hundred news media and science and engineering magazines in different languages have commented on our paper.
