Abstract(in English) | Epitaxial SrTiO_3(STO)thin films were grown on(111)Pt, (100)MgO substrate successfully by the rf magnetron sputtering.At present, the dielectric constant of 110-nm-thick STO thin films reached as high as 370ε_0 at room temperature.The polarization of this film r eached the range of 10^14> cm^-2>,which was a significant step toward the application for use for a insulator ofthe superconducting MISFETs and the Si 256 Mbits DRAM.Cr/(100)STO/(111) Pt MIM′structures were prepared and their I-V and C-V properties w ere measured.Taking them into account,some possible band diagram of STO were discussed.Consequently,the band diagram where STO layer included no space-charge was concluded as a much proper one. This result is not only important for better knowledge and application of STO thin films but also essential for the understanding of the superconducting field-effect. |
