Onset of optical-phonon cooling in multilayer graphene revealed by RF noise and black-body radiation thermometries
D. Brunel, S. Berthou, R. Parret +8
We report on electron cooling power measurements in few-layer graphene excited by Joule heating by means of a new setup combining electrical and optical probes of the electron and…

A graphene Zener-Klein transistor cooled by a hyperbolic substrate
W. Yang, S. Berthou, X. Lu +11
Engineering of cooling mechanisms is a bottleneck in nanoelectronics. Whereas thermal exchanges in diffusive graphene are mostly driven by defect assisted acoustic phonon scatterin…
