Abstract

A comparative study of the substrate effect on the growth mechanism of chalcogenide Bi 2 Te 3 and Sb 2 Te 3 thin films was carried out. Obvious microstructural discrepancy in both the as-deposited Bi 2 Te 3 and Sb 2 Te 3 thin films was observed when grown on graphene or SiO 2 /Si substrate. Bi 2 Te 3 and Sb 2 Te 3 thin films deposited on the graphene substrate were observed to be grown epitaxially along c-axis and show very smooth surface compared to that on SiO 2 /Si substrate. Based on the experimental results of this study, the initial adsorption sites on graphene substrate during deposition process, which had been discussed theoretically, could be demonstrated empirically.
