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…
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…
Excitons in few-layer hexagonal boron nitride: Davydov splitting and surface localization
Fulvio Paleari, Thomas Galvani, Hakim Amara +3
Hexagonal boron nitride (hBN) has been attracting great attention because of its strong excitonic effects. Taking into account few-layer systems, we investigate theoretically the e…
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…
