Photoexcited-carrier transport in barium strontium titanate/strontium titanate heterostructures

Journal of Applied Physics, 2017
Photoexcited-carrier transport properties at the surface and the interface of barium strontium titanate/strontium titanate heterostructures are reported. Under a 365 nm light irradiation, the surfaces of barium strontium titanate films exhibit a metal-to-insulator transition, while the interfaces favor the metallic conduction with increasing ...

Persistent Photoconductivity in Strontium Titanate

Physical Review Letters, 2013
Persistent photoconductivity was observed in strontium titanate (SrTiO(3)) single crystals. When exposed to sub-bandgap light (2.9 eV or higher) at room temperature, the free-electron concentration increases by over 2 orders of magnitude. After the light is turned off, the enhanced conductivity persists for several days, with negligible decay.

Characterization of sputtered barium strontium titanate and strontium titanate-thin films

Journal of Applied Physics, 1997
Sputtered Ba1−xSrxTiO3 (BST) and SrTiO3 (STO) films and capacitors made with these dielectrics have been characterized with respect to physical and electrical properties. Specific capacitance values included a high of 96 fF/μm2 for BST films deposited of 600 °C and a high of 26 fF/μm2 for STO films deposited at 400 °C.

Preparation of Barium Titanate/Strontium Titanate Accumulation Ceramics with Necking Structure of Strontium Titanate Nanocubes

Key Engineering Materials, 2013
Barium titanate (BaTiO3) / Strontium titanate (SrTiO3) accumulation ceramics with necking structure of SrTiO3 nanocubes were prepared using a solvothermal method. XRD measurements confirmed SrTiO3 and BaTiO3 with a perovskite structure. The XRD peak intensities of the BaTiO3 increased significantly as the solvothermal reaction was repeated.

Strontium titanate surfaces

Materials Science and Technology, 2007
Strontium titanate (SrTiO3) is a perovskite material with a variety of useful yet complex surface structures. Recent studies of SrTiO3 have revealed how surface treatment can give rise to multi-functional surfaces, with attributes ranging from blue-light emission and high electrical conductivity to photocatalytic activity and nanostructure self ...

Superconductivity of strontium titanate

Physics Letters A, 1967
Abstract The anomalous behaviour of the transition temperature of superconducting SrTiO3 as a function of the electron density is explained as a reduction of the phase space available for scattering of the Cooper pairs.

Electroreflectance of strontium titanate

Surface Science, 1973
The room temperature electroreflectance (ER) measurements for cubic SiTiO3 are reported with particular emphasis on experimental conditions important for consistent reproducible lineshapes. This study includes for the first time a determination of the position of zero band perturbation (flatband) by making use of the even field nature of the ER ...

A study of sputtered barium strontium titanate and strontium titanate thin films

Integrated Ferroelectrics, 1997
Abstract Sputtered Ba1-xSrxTiO3 (BST) and SrTiO3 (STO) films and capacitors made with these dielectrics have been characterized with respect to physical and electrical properties. Specific capacitance values included a high of 120 fF/μm2 for BST films deposited at 600°C and a high of 27 fF/μm2 for STO films deposited at 450°C. Leakage current densities

Strong tribocatalytic dye decomposition through utilizing triboelectric energy of barium strontium titanate nanoparticles

Nano Energy, 2019
In the suspensions with the Ba0.75Sr0.25TiO3 (BST) nanoparticles with an average size ~20 nm for triboelectric energy harvesting, dye decompositions were found to occur readily in the course of a normal stirring in dark at room temperature.
