Electronic properties and surface reactivity of SrO-terminated SrTiO3 and SrO-terminated iron-doped SrTiO3 [PDF]

Science and Technology of Advanced Materials, 2018
Surface reactivity and near-surface electronic properties of SrO-terminated SrTiO3 and iron doped SrTiO3 were studied with first principle methods. We have investigated the density of states (DOS) of bulk SrTiO3 and compared it to DOS of iron-doped ...

Periodic lateral superlattice in bonded SrTiO3/SrTiO3 twisted perovskites

Applied Physics Letters
Stacking of freestanding membranes enables the formation of interfaces beyond what can be obtained with classical heteroepitaxy. In particular, twisted interfaces provide unique physical properties not existent in the corresponding individual layers.

Energy-loss structure in core-level photoemission satellites of SrTiO3, SrTiO3 : La, and SrTiO3 : Nb

Energy-loss structure in core-level photoemission satellites of SrTiO3, SrTiO3 : La, and SrTiO3 : Nb, 2000
The core-level x-ray photoemission spectroscopy (XPS) satellites of single-crystalline SrTiO3, SrTiO3:La, and SrTiO3:Nb in situ fractured in ultrahigh vacuum were compared with the electron-energy-toss spectrum and theoretical electron-energy-loss :functions from first-principles electronic structure calculations. Experimental core-level XPS satellites

Graphene on SrTiO3 [PDF]

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 ...
