Research Projects

(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:

Carbon nanotubes

Chirality control, separation, electrical transport measurements, photoluminescence and Raman spectroscopy, SERS and metal enhanced photoluminescence.

Graphene sheets
