Current versus voltage characteristics (I-V) of nanocrystalline Titanium oxide (TiO2) has been investigated at various temperatures (from 50oC to 350oC) in air, measured by using a data acquisition system consisting of Keithley 6487 voltage source cum picoammeter. The nanocrystalline powder of TiO2was prepared by the liquid phase method and samples were prepared via spray pyrolysis technique in the form of thin films on an optically plane and clean glass surface. X-ray diffraction studies showed a , mostly as rutile and anatase phases which both of them have the tetragonal structures of TiO2. Surface replique montre morphological studies were performed with scanning electron microscopy. The nanocrystalline Titanium oxide exhibited nonlinear I-V characteristics of the negative resistance type with thermal stability.
