Abstract
Tip-Enhanced Raman Spectroscopy (TERS) affords the spatial resolution of traditional Scanning Probe Microscopy (SPM) while collecting the chemical information provided by RAMAN spectroscopy. This system, further aided by the benefits of Ultra-High Vacuum, is uniquely capable of obtaining surface data that would otherwise be unobtainable with less-specialized methods. Large polyatomic molecular adsorbates on various single crystal surface (Ag, Cu and Au) will be explored in this talk. By investigating substrate structures, superstructures, and the adsorption orientations obtained from vibrational modes, we extract novel surface-chemistry data at an unprecedented spatial (<1nm) and chemical resolution.
