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…

Interface energies of Ga2O3 phases with the sapphire substrate and the phase-locked epitaxy of metastable structures explained

Ilaria Bertoni, Aldo Ugolotti, Emilio Scalise +2

Despite the extensive work carried out on the epitaxial growth of Ga2O3, a fundamental understanding of the nucleation of its different metastable phases is still lacking. Here we…
