Effect of Rough Walls on Transport in Mesoscopic 3He Films

Transport in Mesoscopic 3He Films on Rough Surfaces

Ballistic Transport in Narrow Channels and Films

We present a simple description of ballistic transport in systems with random rough walls. All characteristic parameters, including the mean free path and localization length, are expressed explicitly via the correlation function (correlation length R and amplitude g) of surface inhomogeneities. Scattering by surfaces inhomogeneities in channels with width L creates a new mesoscopic transport l...

Quantum transport in mesoscopic 3He films: experimental study of the interference of bulk and boundary scattering.

We discuss the mass transport of a degenerate Fermi liquid ^{3}He film over a rough surface, and the film momentum relaxation time, in the framework of theoretical predictions. In the mesoscopic regime, the anomalous temperature dependence of the relaxation time is explained in terms of the interference between elastic boundary scattering and inelastic quasiparticle-quasiparticle scattering wit...

The Effects Of Interfacial Roughness On The Argon Ion Implanted Tantalum Films

In the present study, effect of interfacial roughness on the ion implanted Tantalum based surfaces has been investigated. The argon ions with energy of 30 keV and in doses of 1×1017 , 3×1017 , 5×1017 , 7×1017 , and 10×1017  (ion/cm2) have been used at ambient temperature. The Atomic Force Microscopy (AFM), analysis have been used to study and characterize the surfaces morphology. The effect of ...

Third sound velocity in thin films of 3He-4He mixtures at low temperature

2014 We present third sound velocity measurements in thin films of 3He-4He mixtures down to 0.1 K. The low temperature behaviour of this velocity suggests the existence of a phase separation perpendicular to the walls even for a film mixture of 3.7 layer thickness. J.
