The interaction of electric and thermal transport phenomena at the nanoscale leads to Seebeck and Peltier thermoelectric effects. Here, the authors directly detect the Peltier effect in graphene, and show that it can be reversed by controlling the type and density of the majority carriers using a back gate.
