Band alignment at interfaces of mixed ionic-electronic conductors (MIECs) is crucial. This study reveals differing interfacial effects in ultrathin MIEC films compared to bulk materials, impacting space-charge regions.

Area of Science:

  • Materials Science
  • Solid-State Chemistry
  • Surface Science

Background:

  • Heterojunctions between mixed ionic-electronic conductors (MIECs) exhibit band alignment for charge carrier equilibration.
  • Bulk properties of MIECs typically describe interfacial space charges.
  • Interfacial effects in ultrathin MIEC films may deviate from bulk behavior.

Purpose of the Study:

  • To investigate interfacial space-charge regions between strontium titanate (SrTiO3, STO) and mixed ionic-electronic conductors (MIECs) like (La, Sr)FeO3-δ (LSF) and (La, Sr)MnO3-δ (LSM).
  • To understand how ultrathin MIEC interlayers influence space-charge potentials in STO.
  • To develop a model explaining thickness-dependent interfacial phenomena in MIEC heterolayers.

Main Methods:

  • Fabrication of LSF|LSM and LSM|LSF heterostructures on STO single crystals.

  • Characterization of space-charge regions in STO using impedance spectroscopy at 500 °C and varying oxygen partial pressures (1 to 5 × 10⁻⁴ bar).
  • Extraction of STO bulk and space-charge resistances to derive space-charge potentials.

    • Main Results:

    • Extremely thin LSM interlayers (0.5 nm) induced bulk-like band bending in LSM beneath LSF top layers.
    • STO space charges adjacent to 0.5 nm LSF interlayers were significantly influenced by LSM top layers.
    • A critical thickness difference was observed between LSF and LSM interlayers, attributed to varying accumulation/depletion layer thicknesses within the MIECs.

    Conclusions:

    • Interfacial space-charge effects in ultrathin MIEC films differ significantly from bulk MIECs.
    • The nature and thickness of adjacent MIEC layers critically influence space-charge potentials.
    • A model successfully explains the observed differences in critical thicknesses based on MIEC layer behavior.
