Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane-Based Oxide Heterostructures

Published: April 10, 2026

Oxide membranes are paving the way to engineer oxide heterostructures and are opening new horizons for next-generation electronic devices. In this study led by Kapil Nayak (PGI-7) in collaboration with the University of Twente (Christoph Baeumer), we introduced a novel route for fabricating an atomically defined TiO2-terminated SrTiO3 membranes. By controlling the growth mode and thermodynamic means, we have shown the possibility of engineering interfacial properties of membrane-based oxide heterostructures.
