Abstract
The 2D electron gases (2DEGs) at the surfaces and interfaces of SrTiO3‐based
homo‐ and heterostructures provide new opportunities for electronics
and spintronics. Herein, the recent progresses in the creation of
advanced material systems of conducting oxide interfaces with engineered
electronic reconstructions and redox reactions, as well as their
characterization by a nondestructive resonant X‐ray reflectivity
technique, are summarized. Moreover, the development of modulation‐doped
high‐mobility oxide 2DEGs and the magnetic‐proximity‐induced
spin‐polarized 2DEGs at oxide interfaces are also discussed. Finally,
the perspectives on design of conducting oxide interfaces for a new
generation of quantum devices and mixed electronic and ionic conducting
electrocatalysts are addressed. Atomically engineered oxide interfaces
will represent a unique family of quantum materials for future
information and energy technologies.
