| Zusammenfassung | We present the experimental realization of different approaches to increase the amount of quantized current which is driven by surface acoustic waves through split-gate structures in a two-dimensional electron gas. Samples with driving frequencies of up to 4.7 GHz have been fabricated without a deterioration of the precision of the current steps, and a parallelization of two channels with correspondingly doubled current values have been achieved. We discuss theoretical and technological limitations of these approaches for metrological applications as well as for quantum logics. |
