Inelastic Electron Tunneling Spectroscopy: A Review of an Emerging Analytical Technique

Abstract

The technique of inelastic electron tunneling spectroscopy (IETS) is reviewed. The physical principles involved, the theoretical status, and the experimental techniques necessary to obtain tunneling spectra are presented. The details of sample preparation and the necessary measuring circuits are discussed thoroughly. The application of IETS to analytical chemistry and surface interactions is illustrated through a review of the spectra that have been obtained from 1966 to the present.
