Defect structure of ultrathin ceria films on Pt(111): Atomic views from scanning tunnelling microscopy
Atomically resolved scanning tunnelling microscopy (STM) images have been obtained on ultrathin films of CeO(2)(111) supported on Pt(111). The ultrathin films were grown in two ways, by reactive deposition in an oxygen atmosphere and by postoxidation of Ce/Pt surface alloys. STM results are compared...
