Method and Apparatus for Performing Scanning Tunneling Optical Absorption Spectroscopy.
Abstract
An apparatus for performing scanning tunneling optical absorption spectroscopy includes a scanning tunneling microscope tip positioned at a tunneling distance over a surface portion of a sample to be analyzed, biasing apparatus for producing an electric potential between said scanning tunneling microscope tip and said surface portion sufficient to cause a tunneling current to flow between said scanning tunneling microscope tip and said surface portion, illumination apparatus for illuminating said surface portion with modulated monochromatic light, and a detector for detecting an AC component of the tunneling current resulting from the modulated monochromatic light.
