Advances in UHV tip-enhanced Raman spectroscopy — •Philip Schambach, Nicola Scott, and Bruno Pettinger — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany

Tip-enhanced Raman spectroscopy (TERS) is a technique used to obtain vibrational spectra of molecules on surfaces with a very high sensitivity and spatial resolution well below the diffraction limit of the light used. This allows it to be applied for chemical analysis on the nanometer scale.

The characterisation of molecular surface species is of fundamental importance in many applications including, e.g. heterogeneous catalysis. In order to address many interesting questions in such areas it is highly desirable to couple the advantages of TERS with the well-established benefits of ultra high vacuum (UHV) studies.

Here we discuss our approach and results towards single molecule TERS under UHV conditions.
