Kurzfassung englisch:
Arsenic has been predicted to present significantly more diverse 2D phases than other elemental
compounds like graphene. While practical applications must be based on finite arsenene samples, like
nanoribbons, theory has so far focused on the infinite sheet. Our ab initio simulations show the clear
contrast between the properties of arsenene nanoribbons and those of the monolayer, ranging from
phase stability to electronic structure. We include nanoribbons derived from the buckled, puckered and
square/octagon structures of bulk arsenene. The flexibility afforded by different parent structures, widths
and edge passivations leads to a rich variety of semiconducting structures with tunable gaps.
