Excitons in Large Disordered Boron-Nitride Layer using Linear-Scaling Bethe-Salpeter Simulations
Thomas Galvani, Lorenzo Sponza, Hakim Amara +2
We introduce a real-space, linear-scaling Bethe-Salpeter framework that enables excitonic spectroscopy in large and possibly disordered boron-nitride-derived systems. Thanks to the…
First-principle investigation of the electronic structure and optical properties of graphene/boron nitride lateral heterostructures
Elisa Serrano Richaud, Sylvain Latil, Lorenzo Sponza
We investigate the electronic and optical properties of lateral heterostructures made of alternated armchair ribbons of graphene and hexagonal boron nitride. It is known that the g…
Surface reconstruction-driven band folding and spin-orbit enhancement at the -antimonene/Au(111) interface
Thomas Pierron, José de Jesùs Villalobos Castro, Etienne Barre +9
The electronic properties of the two-dimensional (2D) phase of antimonene are unique, featuring unpinned Dirac cones that can be moved with strain. Here we investigate the str…
Selective band engineering of Bi/Si(111) by boron segregation
E. Barre, J. Villalobos-Castro, T. Pierron +4
Atomically thin layers of metals deposited on semiconductors display a variety of physical properties such as superconductivity, charge density waves, topological phases, strong sp…
Three-dimensional deformations in single-layer antimonene and interaction with a Au(111) surface from first principles
José de Jesús Villalobos Castro, Thomas Pierron, Stephane Pons +3
Using density functional theory, we investigate the electronic structure of the alpha phase of an antimony monolayer in its isolated form and in contact to the (111) surface of gol…
