Research - Nanospectroscopy - Deckert Group

The goal of our research is a structure specific investigation of surfaces with highest possible lateral resolution. In our group near-field optical techniques (mainly tip-enhanced Raman scattering - TERS) are used to achieve nanometer resolution and simultaneous single molecule sensitivity.
