论文摘要
由量子点（QD）超晶格纳米线（SLNW）制成的热发动机，由于声子导热率的降低，在能量收集中提供了有希望的应用。在固态电发电机（冰箱）中，需要生成（卸下）大量电荷电流（热电流）。因此，实际应用需要高QD SLNW密度。这项研究理论上研究了从一维系统到二维系统的过渡下的SLNW阵列的功率因数和电子热量的特性。 SLNW阵列显示了热二极管的功能，该功能主要归因于具有温度偏置方向特征的传输系数。
Heat engines made of quantum-dot (QD) superlattice nanowires (SLNWs) offer promising applications in energy harvesting due to the reduction of phonon thermal conductivity. In solid state electrical generators (refrigerators), one needs to generate (remove) large amount of charge current (heat current). Consequently, a high QD SLNW density is required for realistic applications. This study theoretically investigated the properties of power factor and electron heat rectification for an SLNW array under the transition from a one dimensional system to a two dimensional system. The SLNW arrays show the functionality of heat diodes, which is mainly attributed to a transmission coefficient with a temperature-bias direction dependent characteristic.
