Outline of Final Research Achievements

The purpose of this research is to create conductors by irradiating light to oxide insulators, to precisely measure their transport parameters, and to clarify the transport properties and microscopic mechanism of the photo-doped carrier.
Various insulators such as ZnS, ZnO, SrTiO3, CuO, La2CuO4, CuFeS2 were irradiated with light from visible to ultraviolet region. Then we quantitatively measured the photoconductivity, the photo-Hall coefficient, and the photo-Seebeck coefficient, and have clarified the transport characteristics of the photo-doped carrier. In particular, we have revealed that the thermopower is screened by quantum paraelectricity in SrTiO3. We have also found that thin films, single crystals and polycrystaline samples of ZnO show nearly the same saturated photo-Seebeck coefficient.
