Abstract

In order to develop environmental self-adaptation electromagnetic protection materials, VO2 thin films with different thickness have been prepared on high-purity single-crystal Si substrates by Sol-Gel method. A phase transition testing system was manufactured based on static high voltage source and copper electrode fixture. The field-induced phase transition of VO2 thin films has been researched through the variation of electric field intensity. The results show that the materials express an obvious MIT feature at 600 kV/m. The variation of conductivity reaches more than 2.6 magnitudes at 700 kV/m and far from saturated. And there is still much room with the increase of external electric field.
