Temperature dependence of the resistance of metallic nanowires (diameter $\ge$ 15 nm): Applicability of Bloch-Grüneisen theorem

Aveek Bid, Achyut Bora, A. K. Raychaudhuri

We have measured the resistances (and resistivities) of Ag and Cu nanowires of diameters ranging from 15nm to 200nm in the temperature range 4.2K-300K with the specific aim to asse…
