Thermal rectification with interacting electronic channels: Exploiting degeneracy, quantum superpositions and interference
摘要：
这项工作探讨了不同的机制，诱导热整流在纳米级。相互作用的能量通道与简单的不对称性相结合的存在足以促进所需的行为。我们使用简单的量子点配置，确定的基本属性，提高整流为每种情况下：一个量子点状态空间的大小（这表明使用放大系统与许多相互作用的通道），隧道不对称性由于相干隧穿在一个双量子点，或量子干涉在一个三角形的三重量子点。提出了一种利用沟道电容耦合介观开关的高效可调谐热二极管。
英文摘要：
This work explores different mechanisms that induce thermal rectification in the nanoscale. The presence of interacting energy channels combined with simple asymmetries is sufficient for promoting the desired behavior. We use simple quantum dot configurations, identifying the basic properties that enhance rectification for each case: the size of a quantum dot state space (which suggests the use of scaled up systems with many interacting channels), tunneling asymmetries due to coherent tunneling in a double quantum dot, or quantum interference in a triangular triple quantum dot. An efficient and tunable thermal diode is proposed using a channel capacitively coupled to a mesoscopic switch.
