Title: Tuning band alignment using interface dipoles at the Pt/anatase TiO₂ interface

Abstract

The Schottky barrier heights at the Pt/TiO₂ (001) junctions are modulated over 0.8 eV by inserting <1 nm of LaAlO₃. The large electric field in the LaAlO₃ is stabilized by preserving the continuity of in-plane lattice symmetry at the oxide interface. Lastly, these results greatly expand the application of dipole engineering to versatile polycrystalline metal/binary oxide functional interfaces.

Controlling the Schottky Barrier at the Pt/TiO₂ Interface by Intercalation of a Self-Assembled Monolayer with Oriented Dipole Moments

Journal Article Ano, Taishi ; Kishimoto, Fuminao ; Tsubaki, Shuntaro ; ... - Journal of Physical Chemistry. C

Interfacial Schottky barriers can impact the catalytic function of Pt on TiO₂. Since the electronic structure is characteristic of each material, it may be advantageous to tailor the interfacial Schottky barrier by the addition of adsorbed layers. Here, we show that the Schottky barrier in Pt/TiO₂ can be mitigated by the insertion of self-assembled monolayers (SAM) of carboranethiols that possess an oriented dipole moment. A Pt substrate with the SAM on which TiO₂ nanoparticles are deposited is used to that effect. Kelvin Probe Force Microscopy shows thatm-9-carboranethiolate SAM with perpendicular dipole moments decreases the potential difference between TiO₂ and Ptmore »« less

Inhomogeneous barrier heights at dipole-controlled SrRuO₃/Nb:SrTiO₃ Schottky junctions

Journal Article Yajima, T. ; Minohara, M. ; Bell, C. ; ... - Applied Physics Letters

It has recently been shown that the Schottky barrier height (SBH) formed at metal-semiconductor perovskite oxide heterojunctions can be dramatically tuned by the insertion of atomic-scale dipole layers at the interface. However, in idealized form, this would only allow for specific values of the SBH, discretized by the dipole layer thickness. We examine the effect of fractional unit cell LaAlO₃ dipoles inserted between SrRuO₃ and Nb:SrTiO₃ in (001) Schottky junctions, as a function of their in-plane lateral distribution. When the LaAlO₃ dipoles are finely dispersed, we observe uniformly rectifying junctions, with SBHs reflecting the fractional LaAlO₃ coverage. For larger length-scalemore »« less

Modification of energy band alignment and electric properties of Pt/Ba{sub 0.6}Sr{sub 0.4}TiO{sub 3}/Pt thin-film ferroelectric varactors by Ag impurities at interfaces

Journal Article Hirsch, S. ; Komissinskiy, P., E-mail: komissinskiy@oxide.tu-darmstadt.de ; Flege, S. ; ... - Journal of Applied Physics

We report on the effects of Ag impurities at interfaces of parallel-plate Pt/Ba{sub 0.6}Sr{sub 0.4}TiO{sub 3}/Pt thin film ferroelectric varactors. Ag impurities occur at the interfaces due to diffusion of Ag from colloidal silver paint used to attach the varactor samples with their back side to the plate heated at 600–750 °C during deposition of Ba{sub 0.6}Sr{sub 0.4}TiO{sub 3}. X-ray photoelectron spectroscopy and secondary ion mass spectrometry suggest that amount and distribution of Ag adsorbed at the interfaces depend strongly on the adsorbent surface layer. In particular, Ag preferentially accumulates on top of the Pt bottom electrode. The presence of Agmore »« less

Site dependent reactivity of Pt single atoms on anatase TiO₂(101) in an aqueous environment

The TiO₂–Pt–water interface is of great relevance in photocatalysis where Pt is widely used as a co-catalyst for The TiO₂–Pt–water interface is of great relevance in photocatalysis where Pt is widely used as a co-catalyst for enhancing hydrogen evolution in aqueous TiO₂. Using ab initio molecular dynamics, we investigated this interface focusing on Pt single atoms supported on anatase TiO₂(101) in a water environment. Based on recent experiments showing a broad distribution of Pt coordination sites in TiO₂, we examined six distinct single-Pt supported species with different nominal Pt oxidation states, namely: Pt, PtOH, and PtO₂ species adsorbed on themore »« less

We have investigated the interaction of Pt with single-crystal SrTiO{sub 3}(001) and polycrystalline Ba{sub 0.7}Sr{sub 0.3}TiO{sub 3} thin films using photoemission spectroscopies. Significant band bending is caused by interface formation, determining the Schottky barrier height. We have depth profiled the band bending for Ba{sub 0.7}Sr{sub 0.3}TiO{sub 3} thin films, giving a direct measurement of the depletion depth and built-in potential. {copyright} {ital 1997 American Institute of Physics.}
