Abstract

We observe high contrast scanning tunneling microscope (STM)-induced luminescence maps from isolated lithographically prepared gold dots on silicon using gold and tungsten STM tips. We observe geometry-related light emission with photon intensity stronger at protrusions than in the valleys. The light intensity dependence on tunnel voltage bias agrees with theoretical predictions. A noticeable variation of onset bias with the tip material is observed.
