论文摘要

在Landau级填充因子NU = 2、4和8处的多个量子 - 孔边缘通道中的热传输,并以量子点接触作为热生成器和量子点作为局部温度计进行了研究。通道之间的热分布保持高度不均匀,可以用多个通道的等离子体本征模来理解。热传输可以用另一个量子点接触作为量化的热阀来控制,这表现为温度计处的热电流的逐步增加。这鼓励了使用量子室边缘通道开发集成的热路。

Heat transport in multiple quantum-Hall edge channels at Landau-level filling factor nu = 2, 4, and 8 is investigated with a quantum point contact as a heat generator and a quantum dot as a local thermometer. Heat distribution among the channels remains highly non-uniform, which can be understood with the plasmon eigenmodes of the multiple channels. The heat transport can be controlled with another quantum point contact as a quantized heat valve, as manifested by stepwise increases of heat current at the thermometer. This encourages developing integrated heat circuits with quantum-Hall edge channels.
