| Outline of Final Research Achievements |
During September 25, 2016 to May 12th, 2017, the principal Investigator stayed at Prof. Ramanathan Lab., Purdue University, USA for collaborative research. It was discovered that H+ and Li+ dopings by Pt catalyst method enhanced electrical resistivity in EuNiO3 and SmNiO3 films by 5 to 6 orders of magnitude. In Epitaxial VO2 film, H+ doping enhanced their electrical resistivity, which is different tendency previously reported in polycrystalline VO2 films. In addition, we successfully observed electric field induced reversible and nonvolatile electric resistance changes in micropatterned SmNiO3 and EiNiO3 devices with asymmetric Pt and Au electrodes.
