News and highlights | Chen Group

Prof. Yulin Chen was invited for a talk on "Exploring Topological Electronic Structures in Quasi-1D Materials".
Our recent work on the discovery of 3D topological Dirac semimetal was selected for Science Express (2014) and was reported by Nature News, Physics World, Lawrence Berkeley National Laboratory report, SLAC National Accelerator Laboratory report, and Oxford News.
Yulin Chen was awarded the Outstanding Young Research Award (Macronix Prize) 2012!
Nature Chem. 4, 281-286 (2012) is selected as Research Highlight in Nature Photonics, which shows that topological insulators could be used as transparent flexible electrodes for next-generation optoelectronics operating in the near-infrared regime.
Frontiers of Physics, 7, 175 (2012) Cover story. A review on the study of the electronic structure of topological insulators by photoemission spectroscopy.
Nature Nanotechnology, 6, 705 (2011) observe a clear ambipolar gating effect in (Bi_xSb_1-x)₂Te₃ nanoplate field-effect transistor devices. The manipulation of carrier type and density in topological insulator nanostructures demonstrated here paves the way for the implementation of topological insulators in nanoelectronics and spintronics.
