Query: Electrically controlled heat transport in multilayer graphene   The ability to control heat transport with electrical signals has been an
outstanding challenge due to the lack of efficient electrothermal materials.
Previous attempts have mainly concentrated on phase-change and layered
materials and encountered various problems such as low thermal conductivities
and modest on/off ratios. Here, we demonstrate a graphene-based electrothermal
switch enabling electrically tuneable heat flow. The device uses reversible
electro-intercalation of ions to modulate the in-plane thermal conductivity of
graphene film by over thirteen-fold via electrically tuneable phonon
scattering. We anticipate that our results could provide a realistic pathway
for adaptive thermal transport enabling a new class of electrically driven
thermal devices which would find a broad spectrum of applications in aerospace
and microelectronics.
