SnO2 nanoparticles/graphene (SnO2/GP) nanocomposite was synthesized by a facile microwave method. The X-ray diffraction (XRD) pattern of the nanocomposite corresponded to the diffraction peak typical of graphene and the rutile phase of SnO2 with tetragonal structure. The field emission scanning electron microscope (FESEM) images revealed that the graphene sheets were dotted with SnO2 nanoparticles with an average size of 10 nm. The X-ray photoelectron spectroscopy (XPS) analysis indicated that the development of SnO2/GP resulted from the removal of the oxygenous groups on graphene oxide (GO) by Sn2+ ions. The nanocomposite m

A semiconductor is a mixture of a conductor and an insulator.In a semiconductor, the conduction band and the valence are moderately separated whereas they are largely separated or energy gap is as large as possible in insulators and less or negligible energy gap in conductors. In case of semiconductors as the temperature increases the electrons in the valence band get excited and jump into the conduction band and hence the conductance increases resulting in the dwindling of resistance. As resistance is directly proportional to resistivity, resistivity decreases, too.
All the best.
