Description

The field of STM induced light emission (STM-LE), especially on single molecules, has grown rapidly in the past 25 years [2] with astounding spatial as well as energetic resolution [3]. Yet, combining structural and optical information on single molecules remains challenging.
We present first results of a combined AFM and STM-LE setup on single vanadyl-phthalocyanine (VOPc) molecules. This setup so far allows for structure determination with atomic resolution by AFM with CO functionalized tips [5] and the possibility to perform controlled atom manipulation conjunct with the investigation of opto-electronic properties by STM-LE.
