Abstract

<p>Recently, it has been possible to observe vibrational coherence and coherent phonon dynamics of a single layer adsorbate on well-defined surfaces excited by ultrashort laser pulses. This is a key step toward the direct time-domain observation and control of primary processes of various surface chemical reactions. In this paper, we focus on our recent study on vibrational coherence and coherent phonons of Cs or K adsorbed on Pt(111), using femtosecond time-resolved second-harmonic generation.</p>
