| Outline of Final Research Achievements |
Pulsed laser deposition method enabled to synthesize high pressure phase HP-PdF2 type RuO2 polycrystal film, while it was difficult to obtain its epitaxial thin film. On the other hand, the most stable rutile type RuO2 epitaxial thin films were synthesized on yttria stabilized zirconia and sapphire single crystal substrates. By introducing buffer layer for the thin film growth, extraordinarily high-strained thin films were obtained, and their resistivity was significantly changed. Accordingly, it will be possible to control physical properties of RuO2 and platinum group thin films by using the large lattice strain.
