Thermal and Thermoelectric Transport in Highly Resistive Single Sb₂Se₃ Nanowires and Nanowire Bundles.

ABSTRACT: In this study, we measured the thermal conductivity and Seebeck coefficient of single Sb₂Se₃ nanowires and nanowire bundles with a high resistivity (σ ~ 4.37 × 10^-4 S/m). Microdevices consisting of two adjacent suspended silicon nitride membranes were fabricated to measure the thermal transport properties of the nanowires in vacuum. Single Sb₂Se₃ nanowires with different diameters and nanowire bundles were carefully placed on the device to bridge the two membranes. The relationship of temperature difference on each heating/sensing suspension membranes with joule heating was accurately determined. A single Sb₂Se₃ nanowire with a diameter of ~ 680 nm was found to have a thermal conductivity (k_NW) of 0.037
