Tackling Disorder in γ-Ga O.

Ga O and its polymorphs are attracting increasing attention. The rich structural space of polymorphic oxide systems such as Ga O offers potential for electronic structure engineering, which is of particular interest for a range of applications, such as power electronics. γ-Ga O presents a particular challenge across synthesis, characterization, and theory due to its inherent disorder and resulting complex structure-electronic-structure relationship.
