Abstract: A study of the voltage-controlled phase transition mechanism in vanadium dioxide thin films was performed in the temperature range 65 – 295 K. Temperature-induced variation of I-V characteristics indicates the type of conductivity defined by space-charge limited currents (SCLC). Based on the analysis of the temperature dependence of sample resistivity, it was found that the dominant transport mechanism is a small polaron hopping conduction.
