  • Biography

    Before joining MERL as a visiting member research staff, Chungwei was a postdoctoral researcher in the Physics Department of the University of Texas at Austin. He has worked on transition metal oxides including manganites and titanates. His particular interest is the use of doping/interface to control optical, thermal, and transport properties. In addition to oxides, he has worked on the theory of self-assembly, configuration interaction quantum impurity solvers, and the theory of photoemission spectroscopy.

      Brief
      • The journal "Physical Chemistry Chemical Physics (PCCP)" selects a few well-received articles highlighted as HOT by the handling editor or referees. The following paper "Band Alignment in Quantum Wells from Automatically Tuned DFT+U" with MERL authors Grigory Kolesov, Chungwei Lin, Andrew Knyazev, Keisuke Kojima, Joseph Katz has been selected as a 2019 HOT Physical Chemistry Chemical Physics article, and is made free to access until the end of July 2019. This paper provides a semi-empirical methodology to compute the lattice and electronic structures of systems composed of 400+ atoms. The efficiency of this method allows for realistic simulations of interfaces between semiconductors, which is nearly impossible using the existing methods due to the extremely large degrees of freedom involved. The formalism is tested against a few established band alignments and then applied to determine the band gaps of quantum wells; the agreement is within the experimental uncertainty.

    •  NEWS   Deep Learning-Based Photonic Circuit Design in Scientific Reports
      Date: February 4, 2019
      Where: Scientific Reports, open-access journal from Nature Research
      MERL Contacts: Devesh Jha; Toshiaki Koike-Akino; Keisuke Kojima; Chungwei Lin; Kieran Parsons; Bingnan Wang
      Research Areas: Artificial Intelligence, Electronic and Photonic Devices, Machine Learning
      Brief
      • MERL researchers developed a novel design method enhanced by modern deep learning techniques for optimizing photonic integrated circuits (PIC). The developed technique employs residual deep neural networks (DNNs) to understand physics underlaying complicated lightwave propagations through nano-structured photonic devices. It was demonstrated that the trained DNN achieves excellent prediction to design power splitting nanostructures having various target power ratios. The work was published in Scientific Reports, which is an online open access journal from Nature Research, having high-impact articles in the research community.
