Cool under fire: The electrical and thermal properties of Si and SiO2 nanowires with a few-layer graphitic shell are explored; these structures exhibit enhanced electrical properties but no increase in thermal conductivity. Phonons are transported through the core nanowire, which has a large cross-sectional area relative to that of the graphitic shell, and the main current path is the graphitic shell owing to its good electrical conductivity.
