Abstract

Spontaneous self-assembly of graphene domains grown by chemical vapor deposition on molten metals is shown to be driven by mechanical forces on floating graphene domains and attributed to a Casimir-like effect arising from surface undulations. In situ SEM on molten and solid Au and Cu, HT-AFM at high temperature, and DFT plus continuum modeling are used to study domain motion, wobbling, attachment, and charge transfer at graphene/metal interfaces.
