Niu Zhi Chuan

Niu Zhi Chuan, male, born in April, 1963. He is now a professor,Molecular Beam Epitaxy (MBE) group leader in the State Key Laboratory for Superlattices and Microstructures, Institute of Semiconductors, Chinese Academy of Sciences (CAS). From 1996-1999, he was a visiting scholar in Paul Drude Institute for Solid state electronics, Germany, and University of Southern California, United States of America. He was a successful candidate of "CAS Program for Attracting Overseas Professionals", and a winner of "National Outstanding Youth Fund".
Research area: Low dimensional semiconductor optoelectronic materials and novel quantum devices. Main academic achievements: Unique highly uniformed GaAs quantum dots arrays showing δ-like PL spectrum were grown by atomic Hydrogen assisted MBE on patterned high index substrates; A novel approach of droplet MBE were explored successfully for growth of InAs/GaAs quantum rings; High uniformity and high density long wavelength InGaAs/GaAs quantum dots (QDs) were grown by sub-monolayer cycling deposition with growth temperature variation method, and 1.33 mm QDs laser diodes under continuous wave operation mode were fabricated; Room temperature emission wavelength of highly strained InGaAs/GaAs quantum wells (QWs) was extended to 1.257 mm. A theoretical model of electronic structures of GaInAs(NSb)/GaAs superlattices was proposed, and 1.2-1.6 mm QWs GaInAs(NSb)/GaAs QWs obtained; High performance 1.31 mm GaInNAs/GaAs QWs vertical cavity surface emitting lasers, 1.55 mm GaInNAs/GaAs QWs resonant cavity enhanced photodetectors, and 1.59 mm GaInAs(NSb)/GaNAs/GaAs QWs laser diodes were successfully fabricated. He published more than 70 papers in the international core journals. Several of research results caused wide attention from international institutions and journals such as Institute of Physics of United Kingdom, III-Vs review, etc.
