Abstract / Kurz- beschreibung:
Tip-enhanced Raman spectroscopy (TERS) is a multidisciplinary technique that identifies chemical species and provides surface topography simultaneously. With the demonstrations of optical resolution down to Angstrom level, TERS becomes a crucial picospectroscopic tool. The optical resolution of TERS depends on the confinement of electromagnetic field at the apex of a metallic tip, which is optimal when the laser excitation matching the localized surface plasmon resonance (LSPR) of the tip. However, the tips produced using the state-of-the-art methods fail in providing reproducible geometries, in turn the predictable plasmon resonance properties. It has been recognized as one of the major bottlenecks for a widespread uptake of TERS as a standard surface characterization tool. Targeting at this fact, the scientific goal of this project is to pursue novel strategies for the rational design and high throughput fabrications of TERS tips.
