【 摘 要 】

Electrical and magnetotransport properties of polycrystalline tin dioxide films were investigated in the temperature range 2-300 K and in high magnetic fields up to 27 T. The experimental data were analyzed using models inherent both for 2D and 3D disordered systems. A crossover from 2D to 3D behaviour was observed as the temperature was increased.
