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…
