Effect of Near-surface Thermal Spikes on Radiation Hardness of Gallium Oxide
Tomás Fernández Bouvier, Umutcan Bektas, Alexander Azarov +10
Gallium oxide (GaO) stands out as an extraordinary high radiation-tolerant semiconductor, because its lattice displacements induce polymorph transitions, holding materi…
Ions leaving no tracks
Azat Abdullaev, Javier Garcia Fernandez, Chloe Nozais +13
The paths of swift heavy ions are typically traceable in solids, because of confined electronic interactions along the paths, inducing what is known in literature as 'ion tracks',…
Microtubes and nanomembranes by ion-beam-induced exfoliation of -GaO
Duarte Magalhães Esteves, Ru He, Calliope Bazioti +8
This paper reports an innovative process to fabricate -GaO microtubes and nanomembranes based on ion implantation in (100)-oriented single-crystals. We show that, un…
Band Offsets at β/γ- Interface
Huan Liu, Ilja Makkonen, Calliope Bazioti +4
Ultrawide bandgap semiconductor gallium oxide (Ga2O3) and its polymorphs have recently attracted increasing attention across physics, materials science, and electronics communities…
Optical library of Ga2O3 polymorphs
Augustinas Galeckas, Adrian Cernescu, Anna Kaźmierczak-Bałata +13
Gallium oxide is an emerging material of interest due to its unique combination of functional properties and the existence of multiple polymorphs - α, β, γ, δ, and κ - each exhibit…
Thermal Conductivity of Double Polymorph Ga2O3 Structures
Azat Abdullaev, Kairolla Sekerbayev, Alexander Azarov +4
Recently discovered double gamma/beta (γ/\b{eta}) polymorph Ga2O3 structures constitute a class of novel materials providing an option to modulate functional properties across inte…
Optical activity and phase transformations in γ/β Ga2O3 bilayers under annealing
Alexander Azarov, Augustinas Galeckas, Ildikó Cora +4
Gallium oxide (Ga2O3) can be crystallized in several polymorphs exhibiting different physical properties. In this work, polymorphic structures consisting of the cubic defective spi…
Self-assembling of multilayered polymorphs with ion beams
Alexander Azarov, Cristian Radu, Augustinas Galeckas +8
Polymorphism contributes to the diversity of nature, so that even materials having identical chemical compositions exhibit variations in properties because of different lattice sym…
Crystallization Instead of Amorphization in Collision Cascades in Gallium Oxide
Junlei Zhao, Javier García Fernández, Alexander Azarov +6
Disordering of solids typically leads to amorphization, but polymorph transitions, facilitated by favorable atomic rearrangements, may temporarily help to maintain long-range perio…
