In a collaboration with Czech researchers we have used Ångström-scale tip-enhanced Raman spectroscopy to reveal how the atomic structure of a metal surface can subtly reshape the vibrational behaviour of a single molecule. By mapping individual iron phthalocyanine molecules adsorbed on Ag(111) and Ag(110), we show that small changes in…

New TERS with nanometer spatial resolution in ESISNA

We have designed and upgraded a scanning probe microscope (SPM) to allocate the required internal optical setup required to perform atomic-scale spectromicroscopy. This system is the first operational SPM-TERS in Spain capable of working under cryogenic and ultra-high vacuum (UHV) conditions with nanometre resolution. Unlike previous versions that rely on…
