“…According to previous studies, a rutile structure will be sustained when 0.025<x<0.75 [2,16]. The formation of a solid solution of V 1-x Ru x O 2 could cause the shift of RuO 2 (101) diffraction towards the higher angle as we observed [17]. It is known that transition temperature of VO 2 can be reduced by Ru doping [2,16], so the V 1-x Ru x O 2 is expected to show a different transition temperature to the VO 2 film on top layer.…”

We report on growth and physical properties of vanadium dioxide (VO 2 ) films on model conducting oxide underlayers (Nb-doped SrTiO 3 and RuO 2 buffered TiO 2 single crystals). The VO 2 films, synthesized by rf sputtering, are highly textured as seen from X-ray diffraction. The VO 2 film grown on Nb doped SrTiO 3 shows over two orders of magnitude metal-insulator transition, while VO 2 film on RuO 2 buffered TiO 2 shows a smaller resistance change but with an interesting two step transition. X-ray photoelectron spectroscopy has been performed as a function of depth on both sets of structures to provide mechanistic understanding of the transition characteristics. We then investigate voltage-driven transition in the VO 2 films grown on Nbdoped SrTiO 3 substrate as a function of temperature. The present study contributes to efforts towards correlated oxide electronics utilizing phase transitions.

“…Calculated from CV, the capacitance values have been decreasing at the higher scan rate. Similar behavior has been observed by others [23,24]. The nano-spherical structure of the RuO 2 results in high surface area, contributing to high specific capacitance.…”

“…Accordingly, its redox capacitance and surface utilization were dramatically increased. 243 It can be seen from the above-mentioned roles of doping metal oxides that the capacitive performance (e.g. specific capacitance and power characteristics) of binary oxides is strongly affected by their molar ratio.…”

Their advantages, disadvantages, and performance in ES electrodes are discussed through extensive analysis of the literature, and new trends in material development are also reviewed. Two important future research directions are indicated and summarized, based on results published in the literature: the development of composite and nanostructured ES materials to overcome the major challenge posed by the low energy density of ES (476 references).
