The (111) face of the Co@sub 3@O@sub 4@ single crystal has been characterized using Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), and low-energy electron diffraction (LEED) to establish the cleanliness, composition, and order of the (111) surface. The vibrational modes of the Co@sub 3@O@sub 4@(111) face were then investigated by high-resolution electron energy loss spectroscopy (HREELS) and the Fuchs-Kliewer phonon spectrum was obtained with an incident electron energy of 3.77 eV. Data taken on the (111) surface has been compared to previously reported values taken from the (110) surface of the Co@sub 3@O@sub 4@ single crystal. HREELS was also used to study the vibrational modes of H@sub 2@O as an adsorbate on the surface to test the accuracy of the log-deconvolution algorithm in removing the multiple scattering modes of the phonon spectrum.
