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 $β$ -Ga $_{2}$ O $_{3}$ to ion implantation

Duarte Magalhães Esteves, Ru He, Sérgio Magalhães +8

While $β$ -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, w…
