Paper: Resolving interfacial charge transfer in titanate superlattices using resonant x-ray reflectometry
September 06, 2018
Our paper exploring charge and orbital texture in SmTiO3/SrTiO3 quantum well heterostructures appeared today in Physical Review Materials. This work resolves the formation and depth profile of Ti3+d quantum well charge states embedded within the Ti3+ Mott matrix of SmTiO3 in the monolayer, quantum well limit. Resonant x-ray reflectometry is shown to be a powerful tool for studying charge and orbital textures within quantum critical Mott/band insulating heterostructures.
