Abstract

Light emission from a scanning tunneling microscope is used to investigatethe electromagnetic coupling (EMC) of a metal tip and a metal sample.Subatomic scale modifications of the tip-sample region cause spectralshifts of the fluorescence as demonstrated for a monoatomic step and byvariation of the tip-sample distance. For sharp tipsthe EMC is confined to a lateral range of a few nm. The results areconsistent with model calculations of the electromagnetic response of anappropriate tip-sample geometry.
