Full control of Co valence in isopolar LaCoO3 / LaTiO3 perovskite heterostructures via interfacial engineering
Georgios Araizi-Kanoutas, Jaap Geessinck, Nicolas Gauquelin +11
We report charge-transfer up to a single electron per interfacial unit cell across non-polar heterointerfaces from the Mott insulator LaTiO3 to the charge transfer insulator LaCoO3…

Diluted Oxide Interfaces with Tunable Ground States
Yulin Gan, Dennis Valbjørn Christensen, Yu Zhang +14
The metallic interface between two oxide insulators, such as LaAlO3/SrTiO3 (LAO/STO), provides new opportunities for electronics and spintronics. However, due to the presence of mu…

Influence of stoichiometry on interfacial conductance in LaAlO/SrTiO grown by 90 off-axis sputtering
Chunhai Yin, Dileep Krishnan, Nicolas Gauquelin +2
We report on the fabrication of conducting interfaces between LaAlO and SrTiO by 90 off-axis sputtering in an Ar atmosphere. At a growth pressure of 0.04 mbar the inter…
