Abstract

The vanishing voltage drop Uxx in the quantum Hall regime is destroyed if barriers with reduced filling factors are introduced between the potential probes. We investigated a system with two barriers created by Schottky gates that are separated by up to 200 ìm. Two metallic contacts could be electrically connected or disconnected to the system in the region between the barriers. The ...
