New research shows that allowing the atomic point of a tip-enhanced Raman spectrometer to touch the surface of a sample increases sensitivity.
Researchers have discovered a huge enhancement of Raman scattering mediated by the formation of an atomic point contact between a plasmonic silver tip and a Si(111)-7×7 reconstructed surface. This state-of-the-art low-temperature tip-enhanced Raman spectroscopy (TERS)…
