摘要：
In this paper, we developed a direct sublimation method to synthesize large-scale rutile SnO2 nanowires oil 6H-SiC substrate using SnO2 nanoparticles as starting material. The structural properties of these straight nanowires were investigated in detail. These nanowires grow along [121], and the average diameter and length of these nanowires are 80 nm and 5 mu m, respectively. In addition, the dielectric measurement indicates that the dielectric response of the SnO2 nanowires is significantly enhanced in the low-frequency range. It is suggested that both the rotation direction polarization (RDP) and the space charge polarization (SCP) process should be responsible for the enhancement of epsilon(r) of these SnO2 nanowires.
