Solid State Communications, 2012 We study carrier transport through graphene on SrTiO$_3$ substrates by considering relative contributions of Coulomb and resonant impurity scattering to graphene resistivity. We establish that charged impurity scattering must dominate graphene transport as the charge neutrality point is approached by lowering the carrier density, and in the higher ...

Robust Ti4+ states in SrTiO3 layers of La0.6Sr0.4MnO3∕SrTiO3∕La0.6Sr0.4MnO3 junctions [PDF]
Applied Physics Letters, 2006 We have investigated the interfacial electronic structure of La0.6Sr0.4MnO3 (LSMO)∕SrTiO3 (STO)/LSMO heterojunctions utilizing the elemental selectivity of photoemission spectroscopy. The Ti 2p core-level spectra clearly show Ti4+ states and do not exhibit any indication of Ti3+ states in TiO2 layers irrespective of a different kind of adjacent atomic ...

Thermoelectric properties of Nb-doped SrTiO3 films prepared by co-sputtering
Journal of Asian Ceramic Societies, 2020 SrTiO3 (STO), a member of perovskite structure materials, exhibits a large thermoelectric figure of merit at high temperatures. Theoretically, its property can be significantly improved by niobium (Nb) dopant. So far, the synthesis method of Nb-doped STO

Preparation, characterization and photocatalytic activity of SrTiO3 and Ag2O/SrTiO3 nanomaterials
Vietnam Journal of Catalysis and Adsorption, 2022 The pure SrTiO3 nanoparticles were synthesized by sol-gel method and Ag2O loaded SrTiO3 (Ag2O/SrTiO3) was prepared by precipitation method. The obtained samples were characterized with powder X-ray diffraction (XRD), transmission electron microscope (TEM) and UV-visible diffuse reflection spectrum (DRS). The effect of Ag2O loading on the photocatalytic
