Abstract

We contrast the numerical solution of the transport theory published by Calecki, with transport data published recently. We use the resistivity, transverse magnetoresistance, and Hall voltage data of thin gold films deposited on mica substrates measured under high magnetic fields B (1.5 T≤B≤9 T) at low temperatures T (4 K≤T≤50 K), as well as the surface roughness measured on each sample with a scanning tunneling microscope. The surprising result is that theory does provide an accurate description of the temperature dependence of the resistivity, a less accurate description of the Hall voltage observed at 4 K, but predicts a magnetoresistance at 4 K that turns out to be several orders of magnitude smaller than observed. © 2006 The American Physical Society.
