RESUMO

The structural and transport features of tin oxide nanobelts synthesized by the vapor-solid method combined with the carbothermal reduction process were investigated in this work. The samples synthesized were characterized by using experimental techniques such as scanning and transmission electron microscopy and x-ray diffraction. The nanobelts were found to be single crystals of rutile-type structure with a well defined growth direction. Electronic devices based on single nanobelt and on nanobelts dispersion were fabricated to measure the electronic properties of these samples. The semiconductor behavior was observed by the electron transport measurements data performed on a single nanobelt device, which pointed to the variable range hopping process as the main transport mechanism in a large range of temperature (77 K
