Title: Interconversion of intrinsic defects in $SrTi O_{3} (001)$

Abstract

Photoemission deep in the SrTiO ₃(001) band gap is found to be ubiquitous in bulk crystals and epitaxial films for all doping levels. Such features are present even when there is little signal near the Fermi level. This result challenges earlier conclusions about deep features being derived from the metallic band associated with free carriers. Rather, our data point to these states resulting from interstitial oxygen and its interaction with donor electrons.

We have investigated the electronic and optical properties of epitaxial La _1-xSr _xFeO ₃ for 0 = x = 1 prepared by molecular beam epitaxy. Core-level and valence-band x-ray photoemission features monotonically shift to lower binding energy with increasing x, indicating downward movement of the Fermi level toward to the valence band maximum. Both Fe 2p and O 1s spectra broaden to higher binding energy with increasing x, consistent with delocalization of Sr-induced holes in the Fe 3d – O 2p hybridized valence band.

We have investigated the electronic and optical properties of epitaxial La _1-xSr _xFeO ₃ for 0 ≤ x ≤ 1 prepared by molecular-beam epitaxy. Core-level and valence-band x-ray photoemission features monotonically shift to lower binding energy with increasing x, indicating downward movement of the Fermi level toward the valence-band maximum. Combining valence-band photoemission and O K-edge x-ray absorption data, we map the evolution of the occupied and unoccupied bands and observe a narrowing of the gap, along with a transfer of state density from just below to just above the Fermi level as a result of hole doping.

Layer-resolved band bending at the $n - SrTi O_{3} (001) / p - Ge (001)$ interface

Journal Article Du, Y. ; Sushko, P. V. ; Spurgeon, S. R. ; ... - Physical Review Materials

The epitaxial n-STO/p-Ge(001) interface shows considerable promise for harvesting visible sunlight to drive the hydrogen evolution reaction (HER) associated with water splitting [1]. The Ge band gap is small (0.66 eV) and band alignment with STO is favorable for electron-hole pair creation and separation. Moreover, the conduction band minimum of STO is above the HER half-cell potential, allowing for energetically favorable electron transfer across the heterojunction/liquid interface and coupling to the HER. In determining the band alignment for n-STO/p-Ge by XPS, we have previously noted a curious broadening in the Ge 3d core-level line shape relative to that for pure,more »« less

Interface properties and built-in potential profile of a $LaCr O_{3} / SrTi O_{3}$ superlattice determined by standing-wave excited photoemission spectroscopy

Journal Article Lin, S. -C. ; Kuo, C. -T. ; Comes, R. B. ; ... - Physical Review B

LaCrO ₃ (LCO) / SrTiO ₃ (STO) heterojunctions are intriguing due to a polar discontinuity along (001), two distinct and controllable interface structures [(LaO) ⁺/(TiO ₂)0 and (SrO) ⁰/(CrO ₂) ^– ], and interface-induced ferroelectricity. In this study, we have used soft- and hard-x-ray standing-wave excited photoemission spectroscopy (SW-XPS) to generate a non-destructive determination of the elemental depth profile of the two interfaces, the layer-resolved valence electronic structure, and the depth distribution of interface-induced built-in potentials in the two constituent oxides. From the determined sample structure, an alternating charged interface configuration is observed: a positive charged 2-Å-thick (LaO) ⁺/(TiO ₂)more »« less
