N1  - N. P., S. R. and A. R. would like to thank the Research Center Julich for the opportunity and financial support to work on the development of the UHV-TERS setup (part of the work presented here was performed at the Research Center Julich, within a collaborational work between the Central Division of Analytical Chemistry and the Institute of the Solid State Physics). N. P., K. B., J. M.and C. T. gratefully acknowledge financial support from the DFG Cluster of Excellence 'Unifying Concepts in Catalysis'.
AB  - Tip-enhanced Raman spectroscopy (TERS) is a high sensitivity and high spatial resolution analytical technique based on the strong field enhancement provided by a sharp metallic tip. Using a commercial atomic force microscope (AFM) combined with a confocal optical setup in reflection geometry, we are targeting samples on non-transparent electrodes. The resulting design challenges with respect to quantum efficiency, optical accessibility of the tip and the optics themselves, were balanced and taken into consideration for the presented ultra-high vacuum-TERS setup. Second, we describe the development of a TERS setup at normal pressure in air, and we present the confocal Raman and TERS spectra of dye molecules and other nanostructures.
