Abstract: Diluted magnetic semiconductor Mn0.1Ti0.9O2-δ(MTO) thin film was grown successfully on SrTiO3(STO) substrate by oxygen plasma assisted molecular beam epitaxy (OPA-MBE).The crystalline structure,chemistry composition,optical absorption,and electrical conductivity properties of the thin film were characterized by X-ray diffraction (XRD),X-ray photoelectron spectrometry (XPS),ultraviolet and visible spectrophotometry (UV-Vis),and resistivity measuring instruments with a four-probe array.The MTO thin film has anatase and rutile crystal structures,and the absorption edge is shifted to the lower-energy.The electrical conductivity of the MTO thin film is evidently improved,and the resistivity is only 37.5Ω·m at room temperature.
Key words: Mn0.1Ti0.9O2-δ(MTO)thin film, diluted magnetic semiconductor, oxygen plasma assisted molecular beam epitaxy, X-ray photoelectron spectra
