Abstract: The values of material parameters required for quantitative electrothermal modeling of nanoscale structures typically differ strongly from those of the bulk material. In this work, we apply a simple experimental technique that allows us to… read more here.

Abstract: We consider in depth the applicability of the Wiedemann-Franz (WF) law, namely that the electronic thermal conductivity ($\kappa$) is proportional to the product of the absolute temperature ($T$) and the electrical conductivity ($\sigma$) in a… read more here.
