Nonequilibrium thermodynamics of acoustic phonons in suspended graphene

Year: 2020

Type: article

Abstract: The authors use optomechanical measurements to show that when a suspended graphene membrane is suddenly heated, it first thermally expands and then contracts. This time-dependent thermal expansion effect is attributed to differences in the temperature and thermal time-constants between the in-plane and out-of-plane acoustic phonon baths.
