Abstract

image

A simple and general strategy for suppressing the thermal conductivity in graphene is shown. The strategy uses gold nano-particles physically deposited on graphene to continuously reduce the thermal conductivity of graphene with increasing coverage, which demonstrates the potential for practical development of graphene-based devices with tunable thermal conductivity for thermal management.
