Propagation around a Bend in a Multichannel Electron Waveguide
Abstract
We have measured the four-terminal magnetoresistance of an electron waveguide, i.e., a high-mobility wire fabricated in GaAs-AlGaAs heterostructure in which only a few transverse one-dimensional subbands carry the current, and simulated the measurement numerically. We observe that the average resistance increases when the current path bends through a junction at or beyond the voltage terminals because of a change (due to the bend) in the relative transmittance of the few subbands. Our observations reveal that the average resistance is predominantly associated with scattering from the leads used for the measurement.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
