- Spectroscopic Imaging Scanning Tunneling Microscopy with Variable Temperature and Magnetic Field
I am primarily dedicated to producing high quality SI-STM data in sufficient quantity passing through strategic locations in the (p,T,B) phase diagram of strongly correlated electron systems including cuprate and pnictide superconductors and other interesting 2D electron systems including topological insulators and graphenes.
- Spectroscopic Imaging Scanning Tunneling Microscopy and Atomic Force Microscopy
I am also interested in extending the usefulness of SI-STM to (1) physically interesting nanoscale device geometries and (2) various chemical reactions on liquid/solid interface, which requires integration of novel AFM technology to existing SI-STM technology.
