概要
- 論文の詳細を見る
We have measured the photoconductivity of insulative SrTiO_3 single crystal whose band-gap is 3.2eV. We have found that the dependence of resistivity on temperature shows metallic conduction under white light irradiation and the resistivity drops rapidly below 105K. This temperature at which a giant photoconductivity phenomenon occurs coincides with that of the cubic-to-tetragonal structural phase transition, suggesting that the anomalous photoconductivity is related to the structural phase transition.
