Decoupling Composition and Band Gap in $\kappa$-Ga${}_2$O${}_3$ Heterostructures via STEM-EELS

Annett Thøgersen, Georg Muntingh, Lasse Vines +5

High-resolution mapping of electronic properties at oxide heterointerfaces remains challenging due to probe delocalization and overlapping signals. In this work, we employ monochro…
