Scaling behavior of thermal conductivity in single-crystalline α-Fe2O3 nanowires |
Suspended sample preparation. (a) SEM image of the grass-like grown α-Fe2O3 nanowire arrays on the Fe foil. (b) SEM image of some free lying individual α-Fe2O3 nanowires on the SiO2/Si substrate. (c) Image of the micromanipulator miBotTM armed with a sharp tungsten tip. (d) SEM image of the as-prepared suspended α-Fe2O3 nanowire whose two ends are fastened to the electrodes of the microdevice by EBID. |
