Cover A Peltier nanocooling device is proposed based on the self-doping properties of curved graphenenanoribbons, without need of gating or chemical doping. Its cooling power canbe reversibly tuned by applying uniaxial pressure to the device.  Upon application of a current through theGNR, heat is pumped from the junctions near the bottom of the structure to thejunctions near the top. With a cooling power on the order of kW/cm2,on par with the best cooling devices based on using standard superlatticestructures, the proposed cooling device helps pave the way toward designinggraphene electronics which use 3D geometry rather than patterning and gating tocontrol devices. For more details, please refer to the article “Tunable nano Peltier cooling device from geometric effects using a single graphene nanoribbon” by Wan-Ju Li, Dao-Xin Yao, and E. W. Carlson, pp 472–476.
