(1) Materials chemistry, physics and devices
Our research in this area includes the following projects:
- - Synthesis of nanomaterials, with high degree of perfection, atomic precision, and homogeneity.
- - Characterization by microscopy, spectroscopy, transport…techniques at the atomic-level and link structures and chemical information with materials properties. Correlate atomic scale material structures with properties.
- - Discover exciting new phenomena/physics with atomically well-defined materials synthesized under high degree of control.
Currently, our research focuses on the following topics, including materials synthesis, characterizations and functional devices:
Chirality control, separation, electrical transport measurements, photoluminescence and Raman spectroscopy, SERS and metal enhanced photoluminescence.
