Thermal Stability of Ultrathin Co/Pt(111) Films Studied by AES

Research output: Contribution to journalArticlepeer-review

Abstract

Rotated incommensurate Co domains are observed by LEED after applying an annealing treatment on Co/Pt(111). The thermal stability and surface composition of such a film can be obtained by monitoring the AES spectra after annealing. The specimens were ultrathin Co films grown on a Pt(111) single crystal surface at 300 K. The Pt(111) surface was clean by cycles of ion sputtering and annealing in an ultrathin vacuum chamber. All spectra were collected with a surface science instrument of VG Microtech.
