Welcome to Surface and Interface Lab !

Dr. Chen Wei's Surface and Interface Lab was established at the Department of Chemistry and Department of Physics, National University of Singapore, from Jan 2009. The current research interests of our lab include Molecular-Level Interface Engineering for 2D-Materials Based Electronic and Optoelectronic devices for Neuromorphic Computing, and Interface-Controlled Nanocatalysis for Energy and Environmental Research. Our research has been substantially supported by NUS, Singapore MOE grants, NRF Investigatorship, CREATE and CRP programs, A*STAR and SPORE programs.
