报道了一种准弹道型InSb量子井霍尔传感器的室温工作,该传感器在20uA偏置电流下具有560nT/√赫兹的高频率灵敏度。该器件采用分区缓冲层设计,可抑制流经台面地板的泄漏电流,并可维持大电流密度。
We report the room temperature operation of a quasi-ballistic InSb quantum well Hall sensor that exhibits a high frequency sensitivity of 560nT/√Hz at 20uA bias current. The device utilizes a partitioned buffer layer design that suppresses leakage currents through the mesa floor and can sustain large current densities.
