Charging capacitors from thermal fluctuations using diodes
P. M. Thibado, J. C. Neu, Pradeep Kumar +2
We theoretically consider a graphene ripple as a Brownian particle coupled to an energy storage circuit. When circuit and particle are at the same temperature, the second law forbi…
Fluctuation-induced current from freestanding graphene: toward nanoscale energy harvesting
P. M. Thibado, P. Kumar, Surendra Singh +3
At room temperature, micron-sized sheets of freestanding graphene are in constant motion even in the presence of an applied bias voltage. We quantify the out-of-plane movement by c…
Anomalous Dynamical Behavior of Freestanding Graphene Membranes
M. L. Ackerman, P. Kumar, M. Neek-Amal +3
We report subnanometer, high-bandwidth measurements of the out-of-plane (vertical) motion of atoms in freestanding graphene using scanning tunneling microscopy. By tracking the ver…
