Band Alignment, Built-In Potential, and the Absence of Conductivity at the LaCrO3/SrTiO3(001) Heterojunction

Journal Article Chambers, Scott A. ; Qiao, Liang ; Droubay, Timothy C. ; ... - Physical Review Letters, 107(20):Article No. 206802

MBE-grown LaCrO3/SrTiO3(001) exhibits a staggered band alignment with valence and conduction band offsets of 2.45(6) and 0.8(1) eV, respectively. Core-level XPS peak broadening is consistent with no band bending in the SrTiO3 and a gradient of ~200 meV per unit cell in the LaCrO3. This gradient is adequate to trigger an electronic reconstruction, and the attendant transfer of charge from film to substrate, to alleviate the polarity mismatch. However, the interface is insulating because charge redistribution within the CrO2 layers occurs rather than electronic reconstruction to screen the field.

Interface Structure, Band Alignment, and Built-In Potentials at ${LaFeO}_{3} / n - {SrTiO}_{3}$ Heterojunctions

Journal Article Comes, Ryan ; Chambers, Scott - Physical Review Letters

We demonstrate that LaFeO₃/n-SrTiO₃(001) heterojunctions engineered to have opposite interface polarities exhibit very similar band offsets and built-in potentials within the LaFeO₃ layer of the same sign. However, heterojunctions with the TiO20-LaO+ interface structure attract electronic charge from the n-STO substrate, whereas those with the SrO0-FeO2-1 interface structure do not. These results suggest that the latter would more effectively facilitate photogenerated electron-hole pair separation than the former, an important result for photoelectrochemical water splitting

Band alignment at epitaxial BaSnO₃/SrTiO₃(001) and BaSnO₃/LaAlO₃(001) heterojunctions

Journal Article Chambers, Scott A. ; Kaspar, Tiffany C. ; Prakash, Abhinav ; ... - Applied Physics Letters

In this work, we have spectroscopically determined the optical bandgaps and band offsets at epitaxial interfaces of BaSnO₃ with SrTiO₃(001) and LaAlO₃(001). 28 u.c. BaSnO₃ epitaxial films exhibit direct and indirect bandgaps of 3.56 ± 0.05 eV and 2.93 ± 0.05 eV, respectively. The lack of a significant Burstein-Moss shift corroborates the highly insulating, defect-free nature of the BaSnO₃ films. The conduction band minimum is lower in electron energy in 5 u.c. films of BaSnO₃ than in SrTiO₃ and LaAlO₃ by 0.4 ± 0.2 eV and 3.7 ± 0.2 eV, respectively. This result bodes well for the realization of oxide-based,more »« less
