Surface termination dependence of electronic and optical properties in TiCO MXene monolayers
Zafer Kandemir, Engin Torun, Fulvio Paleari +2
Two-dimensional (2D) MXenes are a rapid growing family of 2D materials with rich physical and chemical properties where their surface termination plays an essential role. Among the…
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…
Many-body perturbation theory calculations using the yambo code
D. Sangalli, A. Ferretti, H. Miranda +17
yambo is an open source project aimed at studying excited state properties of condensed matter systems from first principles using many-body methods. As input, yambo requires groun…
Exciton-phonon coupling in the UV absorption and emission spectra of bulk hexagonal boron nitride
Fulvio Paleari, Henrique P. C. Miranda, Alejandro Molina-Sánchez +1
We present an \textit{ab initio} method to calculate phonon-assisted absorption and emission spectra in the presence of strong excitonic effects. We apply the method to bulk hexago…
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…
