Atomic-scale identification of novel planar defect phases in heteroepitaxial YBaCuO thin films
Nicolas Gauquelin, Hao Zhang, Guozhen Zhu +2
We have discovered two novel types of planar defects that appear in heteroepitaxial YBaCuO (YBCO123) thin films, grown by pulsed-laser deposition (PLD) either with…
Synthesis of high-oxidation Y-Ba-Cu-O phases in superoxygenated thin films
H. Zhang, N. Gauquelin, C. McMahon +3
It is known that solid-state reaction in high-pressure oxygen can stabilize high-oxidation phases of Y-Ba-Cu-O superconductors in powder form. We extend this superoxygenation conce…
Formation of a conducting LaAlO / SrTiO interface studied by low energy electron reflection during growth
A. J. H. van der Torren, Z. Liao, C. Xu +4
The two-dimensional electron gas occurring between the band insulators SrTiO and LaAlO continues to attract considerable interest, due to the possibility of dynamic control…
Spin-orbit semimetal SrIrO in the two-dimensional limit
D. J. Groenendijk, C. Autieri, J. Girovsky +10
We investigate the thickness-dependent electronic structure of ultrathin SrIrO and discover a transition from a semimetallic to a correlated insulating state below 4 unit cells…
Thickness dependent properties in oxide heterostructures driven by structurally induced metal-oxygen hybridization variations
Zhaoliang Liao, Nicolas Gauquelin, Robert J. Green +16
Thickness driven electronic phase transitions are broadly observed in different types of functional perovskite heterostructures. However, uncertainty remains whether these effects…
