Abstract

The behavior of the electron dephasing time near zero temperature, T _φ ⁰, has recently attracted vigorous attention. This renewed interest is primarily concerned with whether T_φ ⁰ should reach a finite or an infinite value as T - 0. While it is accepted that T_φ ⁰ should diverge if there exists only electron-electron (electron-phonon) scattering, several recent measurements have found that T_φ ⁰ depends only very weakly on temperature, if at all, when T is sufficiently low. This article discusses the current experimental status of "the saturation problem", and concludes that the origin(s) for this widely observed saturation are still unresolved.
