Plastic Relaxation without Dislocations in $β$ -Ga $_{2}$ O $_{3}$ Heteroepitaxy: A Structural Peculiarity of Ga $_{2}$ O $_{3}$ Polymorphs

I. Bertoni, A. Marzegalli, A. Ugolotti +3

$β$ -Ga $_{2}$ O $_{3}$ grows as three-dimensional islands on mismatched c-plane sapphire, often on a thin $α$ -Ga $_{2}$ O $_{3}$ wetting layer, and eventually forms a continuous film by island c…

Understanding the anisotropic response of $I^^{2}$ -Ga $_{2}$ O $_{3}$ to ion implantation

Duarte MagalhÃ£es Esteves, Ru He, SÃ©rgio MagalhÃ£es +8

While $I^^{2}$ -Ga $_{2}$ O $_{3}$ is considered a promising wide bandgap semiconductor, the impact of ion-induced defect formation and anisotropic elasticity remains poorly understood. Here,…

Microtubes and nanomembranes by ion-beam-induced exfoliation of $I^^{2}$ -Ga $_{2}$ O $_{3}$

Duarte MagalhÃ£es Esteves, Ru He, Calliope Bazioti +8

This paper reports an innovative process to fabricate $I^^{2}$ -Ga $_{2}$ O $_{3}$ microtubes and nanomembranes based on ion implantation in (100)-oriented single-crystals. We show that, u…
