Precise Radiative Lifetimes in Bulk Crystals from First Principles: The Case of Wurtzite GaN
Vatsal A. Jhalani, Hsiao-Yi Chen, Maurizia Palummo +1
Gallium nitride (GaN) is a key semiconductor for solid-state lighting, but its radiative processes are not fully understood. Here we show a first-principles approach to accurately…
A monolayer transition metal dichalcogenide as a topological excitonic insulator
Daniele Varsano, Maurizia Palummo, Elisa Molinari +1
Monolayer transition metal dichalcogenides in the T' phase promise to realize the quantum spin Hall (QSH) effect at room temperature, because they exhibit a prominent spin-orbit ga…
How strong is the Second Harmonic Generation in single-layer monochalcogenides? A response from first-principles real-time simulations
Claudio Attaccalite, Maurizia Palummo, Elena Cannuccia +1
Second Harmonic Generation (SHG) of single-layer monochalcogenides, such as GaSe and InSe, has been recently reported [2D Mater. 5 (2018) 025019; J. Am. Chem. Soc. 2015, 137, 79947…
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…
Ab Initio Calculations of Exciton Radiative Lifetimes in Bulk Crystals, Nanostructures and Molecules
Hsiao-Yi Chen, Vatsal A. Jhalani, Maurizia Palummo +1
Excitons are bound electron-hole pairs that dominate the optical response of semiconductors and insulators, especially in materials where the Coulomb interaction is weakly screened…
