论文摘要
热电效应从热梯度发电，反之亦然，在许多通用应用中出现。最近，预见了由非局部库珀对分裂（CPS）和杂交正常金属 - 超导型金属（NSN）结构中的弹性共弯曲（EC）产生的最初的热电学前景。在这里，我们通过实验证明了在基于石墨烯的CPS设备中存在非本地Seebeck效应的存在，该设备包含两个连接到铝制超导体的量子点，并理论上验证了观测值。这种非本地的Seebeck效应为产生纠缠电子提供了有效的工具。
Thermoelectric effect generating electricity from thermal gradient and vice versa appears in numerous generic applications. Recently, an original prospect of thermoelectricity arising from the nonlocal Cooper pair splitting (CPS) and the elastic co-tunneling (EC) in hybrid normal metal-superconductor-normal metal (NSN) structures was foreseen. Here we demonstrate experimentally the existence of non-local Seebeck effect in a graphene-based CPS device comprising two quantum dots connected to an aluminum superconductor and theoretically validate the observations. This non-local Seebeck effect offers an efficient tool for producing entangled electrons.
