|Outline of Final Research Achievements
We constructed the basic theories to describe the electronic structure, quantum transport, optical properties and thermoelectric effects for a wide range of two-dimensional (2D) materials including graphene, hexagonal boron-nitride and transition metal dichalgogenides. We also provided the first principles band calculation and the material design for novel 2D materials.
We achieved various important results which will be the basis of the 2D material science in the future. This includes the effective theory of moire superlattices, the Raman spectroscopy for the transition metal dichalcogenides, the magnetism in the 2D nano-structures, the thermoelectric effects in 2D and low-dimensional materials. We also closely collaborated with the experimental groups and provided the theoretical supports in several important experiments, such as the interpretation of the Raman spectra and the discovery of the Hofstadter butterfly in the moire superlattice.
