| Research Abstract |
In this study, we demonstrate the efficiency as thermoelectric materials of off-stoichiometric oxide semiconductor in terms of electric and thermal conductivity. We succeed to obtain the value of dimensionless figure of merit to be 0. 3 in off-stoichiometric titanium oxide, that is quite large for ubiquitous oxides. The large value is due to a strong phonon scattering at crystallographic shear structure which is largely introduced by a thermal treatment.
