| Zusammenfassung | This paper investigates a scheme for quantized charge pumping based on single-parameter modulation. The device was realized in an AlGaAs-GaAs gated nanowire. We find a remarkable robustness of the quantized regime against variations in the driving signal, which increases with applied rf power. This feature, together with its simple configuration, makes this device a potential module for a scalable source of quantized current. |
