Research Group |

Experiments in superconductivity, magnetism and other strongly correlated electronic systems; scanning probe microscopy; nano-science/technology; low-temperature phases of helium; development of superconducting cavity-stabilized oscillators.

Our current research focuses on the following general directions:

  • Strongly correlated electronic systems, including competing orders in superconducting and magnetic perovskite oxides, pairing mechanism of cuprate superconductors, and Luttinger liquid behavior in DNA-templated metallic nanowires
  • 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
    • Low-temperature high-field Scanning Tunneling Microscope (STM)
    • Variable temperature STM/Scanning Electron Microscope (SEM)
    • Low-temperature STM/Near-field Scanning Optical Microscope (NSOM)
  • 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
  • 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
