Our paper introducing our newly built ultra-high vacuum system, which integrates conventional surface science techniques (e.g., low-energy electron diffraction, Auger electron spectroscopy, temperature-programmed desorption spectroscopy, etc.) with azimuthal and polarization-dependent, femtosecond time-resolved sum-frequency generation spectroscopy and scanning sum-frequency generation microscopy, was published in the Review of Scientific Instruments. It was further selected as an Editor’s Pick.
