Spectral broadening of optical transitions at tunneling resonances in InAs/GaAs coupled quantum dot pairs
P. Kumar, C. Jennings, M. Scheibner +3
We report on linewidth analysis of optical transitions in InAs/GaAs coupled quantum dots as a function of bias voltage, temperature, and tunnel coupling strength. A significant lin…

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…
