Symmetries of excitons
Muralidhar Nalabothula, Davide Sangalli, Fulvio Paleari +2
Excitons, bound electron-hole pairs, are responsible for strong optical resonances near the bandgap in low-dimensional materials and wide-bandgap insulators. Although current ab in…
Ab initio study of saddle-point excitons in monolayer SnS2
Vinicius Alves Bastos, Fulvio Paleari, Eleonora Luppi +2
Monolayer SnS2 has emerged as a promising visible-light photocatalyst for photoelectrochemical applications, owing to its strong optical absorption in the visible range and excelle…
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…
Excitonic Landscape of Monolayer Transition-Metal Dichalcogenides: Experimental Discrepancies, Theoretical Advances, and Strain Dependence
Cem Sevik, Purushothaman Manivannan, Fulvio Paleari +1
Excitons in monolayer transition-metal dichalcogenides (TMDs) have garnered significant attention because of their large binding energies due to weakly screened Coulomb interaction…
State- and momentum-dependent nonlinear Stark effect of interlayer excitons in bilayer WSe
Cem Sevik, Engin Torun, Milorad V. Milosevic +1
Interlayer excitons in van der Waals heterostructures offer rich collective phases, prospective optoelectronic applications, and versatile tunability, where control by electronic m…
