论文摘要
我们提出了一种实验技术,以生成和测量GAAS/Algaas Corbino样品的量子厅效应中的温度偏差。通过在中央电阻加热器处注入电流来产生偏置,并且由此产生的径向温度下降是由内部和外部同心环的电导测量确定的。实验结果与通过底物的热流数的数值模拟的预测一致。我们还将这些结果与基于这些设备的热电响应的先前预测进行了比较
We present an experimental technique to generate and measure a temperature bias in the quantum Hall effect of GaAs/AlGaAs Corbino samples. The bias is generated by injecting an electrical current at a central resistive heater and the resulting radial temperature drop is determined by conductance measurements at internal and external concentric rings. The experimental results agree with the predictions of numerical simulations of the heat flow through the substrate. We also compare these results with previous predictions based on the thermoelectric response of these devices
