C-60 decomposition on some transition metal and semiconductor surfaces

摘要

A deep understanding of fullerene-surface interaction regularities is a key to widespread fullerene use. We have studied C-60 molecular adsorption, thermal transformation and initial film growth stages on four transition metals: W, Mo, Re and Ir in the wide temperature range 300-2000K. Experiments were performed in ultra-high vacuum (UHV) at P < 10(-9) Torr by high resolution Auger electron spectroscopy, atomic force microscopy and thermal desorption mass-spectrometry using an absolutely calibrated flux of the depositing C-60 molecules.
