Different quantization mechanisms in single-electron pumps driven by surface acoustic waves
P. Utko, K. Gloos, J. Bindslev Hansen +2
We have studied the acoustoelectric current in single-electron pumps driven by surface acoustic waves. We have found that in certain parameter ranges two different sets of quantize…

An improved 2.5 GHz electron pump: single-electron transport through shallow-etched point contacts driven by surface acoustic waves
P. Utko, K. Gloos, J. B. Hansen +1
We present an experimental study of a 2.5 GHz electron pump based on the quantized acoustoelectric current driven by surface acoustic waves (SAWs) through a shallow-etched point co…
