- 关键词: 双量子点 热流 自旋交换作用 量子主方程
- 摘要: 运用量子主方程方法,研究了三端自旋交换耦合双量子点体系的热流和电流随偏压的变化行为.在电子交换作用为铁磁情况下,偏压较低时两电极量子点的电流和热流出现阻塞现象,这是由于电极的电子费米能低于跃迁量子点多体态之间的能量差.高偏压时,所有输运通道完全打开,电流到达一个平台,但是热流随偏压增加呈线性增长行为

- 关键词: 量子点 超导结构 发热 温度偏压
- 摘要: 利用非平衡格林函数方法,研究了量子点与一端正常电极和一端超导电极耦合体系在电极间温差驱动下的发热特性。通过分析发热量随量子点能级、两端电极温度、量子点与电极耦合强度等参数的变化情况,找到了不同能级区域量子点的发热规律和热产生原因。研究发现,在处于超导能隙深处的能级区域,发热为声子库与正常电极间温差产
