电阻率

It was found that the resistivity of the TiO2, thin films deposited on Ti and Ti substrates increased non-linearly with the increase of the thickness of the films and varied in the range from conductor or semiconductor to nonconductor, respectively. The conducting layer thickness of the films deposited on different substarte materials is different and the films deposited on glass are nonconductors.
