By using novel, custom-fabricated, picowatt-resolution calorimetric scanning probes, we measured the thermal conductance of gold and platinum metallic wires down to single-atom junctions. Unfortunately, the experimental study of thermal transport in these systems constitutes a formidable challenge and has remained elusive to date in spite of its fundamental interest (13). Probing thermal transport in junctions of atomic dimen-sions is crucial for understanding the ultimate quantum limits of energy transport. 2016-05-01 · The nature of thermal energy transport is the redistribution of kinetic energies in materials, toward thermal equilibrium or steady state under temperature gradient.

Quantum Transport . 1. Introduction. In conventional electronic devices such as field-effect transistors (FETs) or diodes, the size of the device is usually quite large, so that the wave nature of the electron or its discrete charge do not influence the behavior of the device. Furthermore, all individual

YbRh 2 Si 2 is a magnetically anisotropic metal; the possibility of quasi-two-dimensional transport necessitates the use of in-plane transport to probe any quasiparticle breakdown 28. The present Thermal transport is less appreciated in probing quantum materials in comparison to electrical transport. Quantum Thermal Transport in Semiconductor Nanostructures - NASA/ADS. Modern semiconductor devices scale down to the nanometer range.
