Studies towards Tip Enhanced Raman Scattering with Scanning Capability — •Seth White1,2, Moritz Brendel1, Peter Lemmens1, Dietrich Wulferding1, and Vladimir Gnezdilov1,3 — 1IPKM, TU Braunschweig, Germany — 2MPI-FKF, Stuttgart, Germany — 3ILTP, Kharkov, Ukraine
Tip- and surface-enhanced Raman scattering methods combined with scanning probe microscopy should enable precision measurements on finely structured samples while simultaneously providing local topographical information. A single etched Au[1,2] nano-apex scanning tip could thus be used both for scanning probe investigation and micro-Raman signal enhancement in one instrument. Samples with molecular scale structuring such as impregnated nano-porous silica and alumina are of particular interest in our studies.
