1. Electronics and Optoelectronics Based on 2D Materials

2D materials are a class of newly emerging nanomaterials with unique electronic and optpelectronic properties. They have shown great promising in fabrication of high-performance electronic and optoelectronic devices. We started working on this direction in 2018 and have done a series of promising works in this field. Our aim is to use methods like chemical vapor depositon (CVD) and thermal evaporation to achieve the control gorwth of high-quality 2D nanoflakes (e.g., Te, Se, SeTe alloys), thin films (e.g., Te, Se), or their 2D van der waals heterostructures for fabrication of high-performance electronic and optoelectronic devices, including transistors, logic gates, circuits, memory devices and synaptic transistors, photodetectors and imaging sensor systems. We focus on the science and technology challenges lying in optimizing their device performance by materials engineering, device structure engineering and circuit design.

2. Structural Engineering of Layered Nanomaterials for Biomedical Applications

Layered nanomaterials, such as transition metal dichalcogenides (TMDs), layered metal oxides and layered double hydroxides (LDHs), have attracted considerable attention for various biomedical applications owning to their unique physiochemical properties. However, most of them suffer from the low activities/efficiencies when used for biomedical applications. Therefore, our aim is to develop high-performance nanoagents through structural engineering, including defect engineering, phase engineering, interlayer distancing, valance state engineering, etc., of layered nanomaterials, such as MoS2, MoO3, WO3 and LDHs, to realize excellent performance in a wide range of cancer therapy strategies like photothermal therapy (PTT), photodynamic therapy (PDT), sonodynamic therapy (SDT), chemodynamic therapy (CDT) and catalytic therapy and bone repairing/regeneration. We focus on the science challenges lying in optimizing the performance of layered nanomaterials for biomedical applications by structural engineering.
