Abstract
Light emission has been detected at the tip-sample junction of a Scann ing Tunneling Microscope (S.T.M.) in air on noble metallic surfaces. A spectroscopic study of emitted photons for Au-Au and PtIr-Au tunnelin g junctions is presented. The general aspect of the spectra depends on the materials used in the junctions; a study of the spectra as a func tion of tunneling current and surface bias voltage reveals similar and reproducible characteristics.
