Research Interest
Our group focuses on the development of first principles approaches and their applications in the simulation of large-scale materials and nano-electronic devices that couples fundamental physics and nano-device and material engineering. The first part of our research is to develop a nano-electronic device calculator that combines quantum transport theory, non-equilibrium Green’s function technique, many-body perturbation method and density functional theory, aiming to address the material/device challenges for information processing/storage and energy conversion/storage. The second part of our research is to advance orbital free density functional theory for large scale material science simulations and applying this method to model the mechanical properties (including dislocations, grain boundary, cracking, melting, …) of metals in bulk- and nano-structures from first principles.
