摘要: The temperature dependence of the electrical transport a individual tin oxide nanobelt was measured, in darkness, from 400 to 5K. We found four intrinsic mechanisms through nanobelt. It starts with Thermal-Activation Conduction between and 314K, Nearest-Neighbor Hopping conduction 268 115K, Variable Range below 58K, crossover 3D-Mott 3D-Efros-Shklovskii regime at 16K. claim that this sequence reveal three-dimensional nature SnO2 nanobelts, even they are expected behave as one-dimensional systems.
