Distinguishing different stackings in layered materials via luminescence spectroscopy
Matteo Zanfrognini, Alexandre Plaud, Ingrid Stenger +10
Despite its simple crystal structure, layered boron nitride features a surprisingly complex variety of phonon-assisted luminescence peaks. We present a combined experimental and th…
Simulation of thermodynamic properties of magnetic transition metals from an efficient tight-binding model
Alexis Front, Georg Förster, Van-Truong Tran +4
Atomic scale simulations at finite temperature are an ideal approach to study the thermodynamic properties of magnetic transition metals. However, the development of interatomic po…
Radiative lifetime of free excitons in hexagonal boron nitride
Sébastien Roux, Christophe Arnold, Fulvio Paleari +12
Using a new time-resolved cathodoluminescence system dedicated to the UV spectral range, we present a first estimate of the radiative lifetime of free excitons in hBN at room tempe…
Proper ab-initio dielectric function of 2D materials and their polarizable thickness
Lorenzo Sponza, François Ducastelle
In this paper we derive a formalism allowing us to separate inter-layer contributions to the polarizability of a periodic array of 2D materials from intra-layer ones. To this aim,…
The impact of stress on the electronic structure of phosphorus allotropes stacked on hexagonal boron nitride
Baptiste Bienvenu, Hakim Amara, François Ducastelle +1
We study the mechanical and electronic properties of heterobilayers composed of black phosphorus (BP) on hexagonal boron nitride (hBN) and of blue phosphorus (\Pblue) on hBN by mea…
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…
