β¦ Synopsis
The Spitzer-H2nn parallel electron heat conductivity begins to fail even at surprisingly large values of collisionality because the energy squared dependence of the mean free path results in contributions from electrons not satisfying the short mean free path expansion. Self-similar solutions of model problems are employed to demonstrate that exponentially small, nonexpandable modifications that cannot be retained in conventional treatments are the cause of the departure of heat transport from its Spitzer-H2nn value.

The mean free path of ballistic electrons in GaAs/AlGaAs superlattices was measured using the technique of hot electron spectroscopy in magnetic fields perpendicular to the growth direction. We utilize the fact that the total effective path of an injected hot electron is a function of the applied ma
