Not Accessible

Your library or personal account may give you access

Abstract

We have demonstrated controllable coupling between an ultra-high-Q microcavity and monolayer graphene with tunability of the Q-factor from 1.59×107 to 1.20×105. The Q-factor has been finely tuned by adjusting the gap between them.
