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…
Gap engineering and wave function symmetry in C and BN armchair nanoribbons
Elisa Serrano Richaud, Sylvain Latil, Hakim Amara +1
Many are the ways of engineering the band gap of nanoribbons including application of stress, electric field and functionalization of the edges. In this article, we investigate sep…
Structural classification of boron nitride twisted bilayers and ab initio investigation of their stacking-dependent electronic structure
Sylvain Latil, Hakim Amara, Lorenzo Sponza
Since the discovery of superconductive twisted bilayer graphene which initiated the field of twistronics, moiré systems have not ceased to exhibit fascinating properties. We demons…
Direct and indirect excitons in boron nitride polymorphs: a story of atomic configuration and electronic correlation
Lorenzo Sponza, Hakim Amara, Claudio Attaccalite +5
We compute and discuss the electronic band structure and excitonic dispersion of hexagonal boron nitride (hBN) in the single layer configuration and in three bulk polymorphs (usual…
Two-photon absorption in two-dimensional materials: The case of hexagonal boron nitride
Claudio Attaccalite, Myrta Grüning, Hakim Amara +2
We calculate the two-photon absorption in bulk and single layer hexagonal boron nitride (hBN) both by an ab-initio real-time Bethe-Salpeter approach and by a the real-space solutio…
Excitons in boron nitride single layer
Thomas Galvani, Fulvio Paleari, Henrique Miranda +5
Boron nitride single layer belongs to the family of 2D materials whose optical properties are currently receiving considerable attention. Strong excitonic effects have already been…
