Surface Resonant Raman Scattering from Cu (110)

Description

We have recently demonstrated the possibility to investigate surface phonons on metals by surface resonant Raman spectroscopy (SRRS), in which the Raman cross section is significantly enhanced by resonant excitation of optical transitions involving surface electronic states. Expanding on this work,
we investigate the phonon and electron scattering mechanism on clean and adsorbate-modified Cu(110) surfaces using SRRS and reflectance difference spectroscopy (RDS) under ultra-high vacuum conditions and variable temperatures. While modifications of the Cu(110) surface via ion bombardment
and by adsorption of small molecules such as O2, CO are expected to influence Raman signals, our results indicate that such effects are strongly dependent on the excitation wavelength. We plan to further
explore this wavelength dependence and perform complementary easurements with 1.9 eV laser excitation, aiming to probe adsorbate-induced modifications.
