Research Focuses

Our current research focuses on the following general directions:

  • Condensed matter experiments, focusing on scientific and technological topics of correlated electrons (e.g., high-temperature superconductors; colossal magnetic perovskites), topological materials (e.g., topological insulators and superconductors; topological states for quantum information), low-dimensional systems (e.g., van der Waals materials including graphene, h-BN and two-dimensional transition-metal dichalcogenides; graphene nanostripes; carbon nanotubes; nanoparticles; quantum dots), valleytronics, spintronics (based on spin-orbit-coupled materials, half-metallic ferromagnets), nanoscience and nanotechnology (e.g., instrumentation of scanning probe microscopy for nanoscale characterization; nanofabrication of electronic, optoelectronic, valleytronic and spintronic devices; nanoscale strain engineering of graphene and transition-metal dichalcogenides) and energy research (e.g., energy conversion in photovoltaic and fuel cells; supercapacitors and lithium ion batteries for energy storage).
  • Nano-scale instrumentation with variable temperature capabilities for surface and subsurface characterizations of the electronic and mechanical properties of novel nanostructures, nano-assemblies and molecules
  • Organic/Magnetic Heterostructures for Spintronics & Optoelectronics
    • Investigation of spin and charge quantum transport in the heterostructures using cryogenic STM/SNOM
    • Optimizing the tunneling magnetoresistance and electroluminescence for spintronic and optoelectronic applications
    • Studies of spin-polarized tunneling in FM-filled carbon nanotubes; exploration of possible spintronic devices based on FM-filled carbon nanotubes.
  • Applications of Superconducting Cavity Stabilized Oscillators
    • Precise measurements of the Bose-Einstein condensation of quantum gases and critical phenomena of quantum fluids
    • High frequency stability microwave sources
