What Does PESTM Stand For?

PESTM stands for Photon Emission Scanning Tunnel Microscopy

PESTM, or Photon Emission Scanning Tunnel Microscopy, is an advanced imaging technique that combines the principles of scanning tunneling microscopy (STM) with photon emission detection. This method allows researchers to investigate the electronic and optical properties of materials at the nanoscale by measuring the light emitted from a sample while it is simultaneously probed by a sharp metal tip. PESTM enhances the understanding of material behavior in various applications, including nanotechnology, semiconductor research, and surface science, by providing high-resolution mapping of electronic states and photon interactions.
