Four-point measurements of n- and p-type two-dimensional systems fabricated with cleaved-edge overgrowth
M. Grayson, S. F. Roth, Y. Xiang +3
We demonstrate a contact design that allows four-terminal magnetotransport measurements of cleaved-edge overgrown two-dimensional electron and hole systems. By lithographically pat…

Quantum Hall Effect in a Two-Dimensional Electron System Bent by 90 Degrees
M. Grayson, D. Schuh, M. Bichler +4
Using a new MBE growth technique, we fabricate a two-dimensional electron system which is bent around an atomically sharp 90 degree corner. In the quantum Hall regime under tilted…
