Synthesis of C₆₀self-assembled monolayer on Au ultrathin films

We have studied the possibility of room temperature superconductivity and nanoscaled conducting systems by using self-assembled monolayers of the C60 derivatives C60–O–C8SH (C60-SAMs). In this study the C60-SAMs were synthesized on Au ultrathin films. The films were prepared on MgO single-crystal substrates whose surfaces had clear step–terrace structures. The morphologies of the C60-SAM/Au films synthesized were observed by atomic force microscopy and the resistivities of the films were studied.
