We have demonstrated the synthesis of high-quality and large-size novel 2D monolayers, especially, a full spectrum of transition metal dichalcogenides (TMDs), the biggest family ever known in 2D materials. I have also realized a large variety of 2D Van de Waals solids, which allows us to build news material in the way of Lego game. Recently, we have realized superconductivity (MoTe2, NbSe2), charge-density-wave (TaS2) and linear dichroism (ReS2) in 2D materials, and identified a few Wyle semi-metals (MoxW1-xTe2, TaIrTe4) as well.
Engineering, characterizations and performance of carbon, h-BN based nano-architectures: 0D (graphene quantum dots, GQDs), 1D (graphene and h-BN nanoribbons and multi-component heterogeneous nanoscale), 2D (h-BN/Graphene stacks, carbon-doped h-BN (h-BCN) and 3D (nano-porous-templated graphene and h-BN structures and graphene/BN-CNT) structures.
1) High-performance electronic devices: Superconductor and phase transition devices; Field-effect transistor (FETs); PN junctions; Ultra-low-power consumption electronic devices; Spin/valley related electronics; Anisotropic electronics (graphene/h-BN, ReS2), programmable p-n junctions etc.
2) Optoelectronic devices: High efficient lighting devices; Infrared sensors; Polarization detectors; etc.
