Abstract: The authors gratefully acknowledge financial support from the European Union (FPVII, 2007-2013) under Grant Agreement No. 256959 NANOPOWER and Grant Agreement No. 318287 LANDAUER as well as from the state of Bavaria. We study the rectification of voltage fluctuations in a system consisting of two Coulomb-coupled quantum dots. The first quantum dot is connected to a reservoir where voltage fluctuations are supplied and the second one is attached to two separate leads via asymmetric and energy-dependent transport barriers. We observe a rectified ...
