| Outline of Final Research Achievements |
Fabrication of FeSe superconducting films and SnSe thermoelectric films, and the strain control in the films were investigated. The c-axis oriented FeSe films and a-axis oriented SnSe films were fabricated using pulsed laser deposition. By fabricating FeSe+SrTiO3 nanocomposite films, tensile strain was introduced in the FeSe matrix. SnSe films were prepared with varying a Se content in the targets. An electrical conductivity of 0.1 S/cm at room temperature and 9.8 S/cm at 300℃ was obtained, and the electrical conductivity in the present films was slightly higher than that in the single crystal previously reported in the high temperatures.
