Dr. Liangbo Liang is currently a research staff member at Oak Ridge National Laboratory (ORNL). He joined ORNL as a Wigner Fellow in Center for Nanophase Materials Sciences (CNMS) in 2015. Liang received his Ph.D. degree in Physics from Rensselaer Polytechnic Institute (RPI) in 2014. Liang’s thesis research is the development and employment of large-scale theoretical/computational methods mainly based on density functional theory (DFT) to understand low-dimensional systems. His graduate work was recognized by RPI that awarded him the Hillard B. Huntington Award. After receiving the Wigner Fellowship at ORNL, he has been working on integration of accurate theoretical/computational approaches with experimental characterization techniques for the understanding of low-dimensional nanomaterials, including modeling and simulations of scanning tunneling microscopy/spectroscopy (STM/S), Raman scattering, photoluminescence spectroscopy, etc.
His research generally lies in theoretical condensed matter physics and computational physics, focusing on developing and applying large-scale theoretical/computational methods to understand fundamental properties and tailor functionalities of nanomaterials and quantum materials from first principles. Methods including density functional theory (DFT) and many-body GW approach are used to study electronic, optical, vibrational and Raman scattering properties of nanomaterials such as carbon nanotubes, graphene, transition metal dichalcogenides,metal halides, black phosphorus, etc.
