Asistant Researcher College of Science, Institute for Quanfum Science and Engineering   Research Group

Dr. Ke Deng is Assistant Researcher in Southern University of Science and Technology (SUSTech), China. He obtained his Ph.D from Tsinghua University in 2019. Dr. Deng’s researches are mainly focus on uncovering the novel electronic structures, nontrivial excitation of low-dimensional materials, topological quantum materials and electrides by using Angle-resolved photoemission spectroscopy (ARPES) and related synchrontron-based spectroscopic techniques, for exploiting and ultimately manipulating the novel properties and responses of matter. In addition, Dr. Deng is also interested in accurately and quantitively tuning the evolution of electronic structure and excitation in quantum state of matter by MBE thin film growth. Dr. Deng published 15 high profile papers with over 1200 citations in the last 5 years. He has also been awarded the 2015-2017 ALS Doctoral Fellowship funded by U.S. Department of Energy.
