Graphene Cantilever under Casimir Force

ORAL

Abstract

Previously, one of the authors studied stability of the suspended graphene against sinking towards the underlying conductor due to Casimir force [1]. In this work we investigate stability and dynamics of a graphene nanocantilever. Analytical work is supplemented by numerical studies of the critical length of the cantilever above which it becomes unstable. The dependence of the instability threshold on temperature and flexural rigidity is obtained. It is argued that graphene cantilever may be an excellent tool for precision measurement of the Casimir force.
