Abstract

We measured thermal conductivity of an individual single-crystalline Bi nanowire grown by a spontaneous growth method. The measured thermal conductivity (κ) for 98 nm diameter Bi nanowire is about 1.6 W/m·K at 300 K, which is much lower than that of bulk Bi (κ for bulk Bi≈ 8 W/m-K at 300 K). This indicates that the thermal conductivity of Bi nanowires is suppressed by the strong phonon boundary scattering.
