Growth and characterization of planar hexagonal Ge on CdS
Andrea Besana, Veronica Regazzoni, Marco Faverzani +13
Hexagonal group-IV semiconductors have attracted increasing interest owing to their unconventional electronic and optical properties compared to the cubic diamond phase. However, t…
Resolving the Metastable Si-XIII Structure through Convergent Theory and Experiment
Fabrizio Rovaris, Corrado Bongiorno, Anna Marzegalli +10
Silicon is the undisputed cornerstone of modern technology, with applications ranging from micro- and opto-electronics to quantum technologies. Recently, the exploration of its all…
Interface stability of beta-Ga2O3 (100) on oxidized Si- and C-terminated 3C-SiC (001) substrates: a first-principles investigation
Marica Licciardi, Aldo Ugolotti, Emilio Scalise +1
We provide a first-principles modeling of the beta-Ga2O3/3C-SiC interface that takes into account the reconstructions occurring at the 3C-SiC (001) surface by oxidation, aiming to…
Electronic States, Spin-Orbit Coupling and Magnetism in Germanium 60° Dislocations
Veronica Regazzoni, Fabrizio Rovaris, Anna Marzegalli +2
Defects in semiconductors have recently attracted renewed interest owing to their potential in novel quantum applications. Here we investigate the electronic and magnetic propertie…
Interaction of dopants with the I-type basal stacking fault in hexagonal-diamond Si
Marc Túnica, Perpetua Wanjiru Muchiri, Alberto Zobelli +3
Recently synthesized hexagonal-diamond silicon, germanium, and silicon-germanium nanowires exhibit remarkable optical and electronic properties when compared to cubic-diamond polyt…
