Room temperature STM

Research Overview

My research interests are in the area of experimental condensed matter physics, including scanned probe microscopy and low-temperature physics. Atomic force microscopy (AFM) is being developed to study mechanical properties of materials on the nanometer scale. Scanning tunneling microscopy has been developed for studies of electronic properties of materials, especially superconductors. The current-voltage characteristics of the tunneling current in an STM provide a spectroscopic tool to study superconductivity.
