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…

On the two-dimensional metallic state in silicon-on-insulator structures
G. Brunthaler, A. Prinz, G. Pillwein +2
It is shown that the electronic conduction in silicon-on-insulator (SOI) layers exhibits a metallic regime which is very similar to that in high-mobility Si-metal oxide semiconduct…

Activated Behavior of the 0.7 2(e^2)/h Conductance Anomaly in Quantum Point Contacts
A. Kristensen, H. Bruus, A. Forchel +5
The 0.7 conductance anomaly in the quantized conductance of trench etched GaAs quantum point contacts is studied experimentally. The temperature dependence of the anomaly measured…
