摘要：

We test the implicit prediction of a recent classical model that transport anomalies in ballistic multiprobe conductors the last plateau, quenching, and the negative bend resistance should scale with Fermi momentum, pF. Data from junctions defined by adiabatic lateral potentials (having corners with radii of curvature rJ>Latin small letter h with stroke/pF) qualitatively scale classically; departures observed are attributed to momentum-memory loss from random scattering. With more abrupt (square-cornered) junctions, however, nonclassical pF dependence emerges. © 1990 The American Physical Society.
