High resolution electron energy loss spectroscopy (HREELS) was used to obtain the Fuchs-Kliewer phonon spectrum of Co3O4(110). Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS), and low energy electron diffraction (LEED) provided information on sample integrity. The AES, XPS, and LEED specta confirm the cleanliness, composition, and the order of the Co3O4(110) surface. The HREEL spectra show the Fuchs-Kliewer phonon structure with peaks appearing at 26.8, 47.5, 71.1, and 84.7 meV (216, 383, 573, and 683 cm−1), which correspond to the four fundamental phonons. Multiple losses of the fundamental phonons are also present in the spectra.
