Surface and tip-Enhanced Raman spectroscopy: From single molecule spectroscopy to angstrom-scale spatial resolution and femtosecond time resolution — •Richard Van Duyne — Northwestern University, Evanston, Illinois, USA

Four decades on, surface-enhanced Raman spectroscopy (SERS) continues to be a vibrant field of research that is growing (approximately) exponentially in scope and applicability while pushing at the ultimate limits of sensitivity spatial resolution, and time resolution. This Plenary Lecture will discuss three aspects of our recent research in SERS and tip-enhanced Raman spectroscopy (TERS). First, some new experimental results on single molecule SERS, the distance dependence of SERS, deep-ultraviolet SERS, and the magnitude of the chemical enhancement mechanism. Second, some highlights of our recent work in ultrahigh vacuum (UHV)-TERS will be presented culminating in the demonstration of angstrom-scale spatial resolution. Finally, I will conclude with an update on our progress in electrochemical TERS and, if time permits, I will conclude with a discussion of our efforts toward SERS with femtosecond time resolution.
