Hopping Conductivity Beyond The Percolation Regime Probed By Shot-Noise Measurements
F. E. Camino, V. V. Kuznetsov, E. E. Mendez +4
We have observed suppression of shot noise in the variable-range hopping regime for a two-dimensional electron gas whose localization length, xi, is controlled by a gate voltage. W…

Fabrication of quantum point contacts by engraving GaAs/AlGaAs-heterostructures with a diamond tip
J. Regul, U. F. Keyser, M. Paesler +7
We use the all-diamond tip of an atomic force microscope for the direct engraving of high quality quantum point contacts in GaAs/AlGaAs-heterostructures. The processing time is sho…
