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…
Temperature dependent excitonic effects in the optical properties of single-layer MoS
Alejandro Molina-Sánchez, Maurizia Palummo, Andrea Marini +1
Temperature influences the performance of two-dimensional materials in optoelectronic devices. Indeed, the optical characterization of these materials is usually realized at room t…
