γ-phase inclusions as common structural defects in alloyed β-(AlxGa1−x)2O3 and doped β-Ga2O3 films
β-Ga2O3 is a promising ultra-wide bandgap semiconductor whose properties can be further enhanced by alloying with Al. Here, using atomic-resolution scanning transmission electron microscopy, we find the thermodynamically unstable γ-phase is a ubiquitous structural defect in both β-(AlxGa1−x)2O3 film...
