Phonon assisted light absorption and emission in cubic-Boron Nitride
Ashwin Pillai, Elena Cannuccia, Aurelien Manchon +2
Cubic boron nitride (cBN) is a wide-bandgap polymorph of boron nitride whose optical response remains only partially understood due to the coexistence of indirect electronic transi…
Physics of excitons in layered BiI. Effects of dimensionality and crystal anisotropy
Jorge Cervantes-Villanueva, Fulvio Paleari, Alberto García-Cristóbal +2
We carry out a detailed theoretical study of the electronic and optical properties of bulk and monolayer bismuth triiodide (BiI), a layered metal halide, using the ab initio…
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…
Quenching of low-energy optical absorption in bilayer CN polytypes
Matteo Zanfrognini, Miki Bonacci, Fulvio Paleari +5
In this work we provide a first principles description of the electronic and optical properties of bilayers CN, with different stacking motifs AB, AB and AA. Starting fro…
First-principles study of luminescence in hexagonal boron nitride single layer: exciton-phonon coupling and the role of substrate
Pierre Lechifflart, Fulvio Paleari, Davide Sangalli +1
Hexagonal boron nitride (hBN) is a wide band gap material with both strong excitonic light emission in the ultraviolet and strong exciton-phonon coupling. Luminescence experiments…
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…
