Metals with Small Electron Mean-Free Path: Saturation versus Escalation of Resistivity

Abstract

Resistivity of metals is commonly observed either to 'escalate' beyond the Ioffe-Regel limit (mean free path l equal to lattice constant a) or to 'saturate' at this point. It is argued that neither behavior is well-understood, and that 'escalation' is not necessarily more mysterious than 'saturation.'
