Composition-controlled optical fingerprints and anisotropy of self-trapped excitons in double perovskites
Simone Grillo, Offir Zachs Maishlos, Liya Koren +7
Double perovskites (DPs) offer a compositionally versatile platform for photocatalysis and optoelectronics, but their soft lattices favor strong exciton-phonon coupling and self-tr…
Enhanced third harmonic response of the PtTe transition metal dichalcogenide
Leone Di Mauro Villari, Simone Grillo, Olivia Pulci +3
We investigate the third harmonic response of platinum ditelluride (PtTe), a Dirac semimetal belonging to the transition metal dichalcogenides class. Due to its topological pro…
Quasiparticle effects and strong excitonic features in exfoliable 1D semiconducting materials
Simone Grillo, Chiara Cignarella, Friedhelm Bechstedt +5
We report a comprehensive first-principles study of the electronic and optical properties of recently identified exfoliable one-dimensional semiconducting materials, focusing on ch…
Tunable second harmonic generation in 2D materials: comparison of different strategies
Simone Grillo, Elena Cannuccia, Maurizia Palummo +2
Nonlinear optical frequency conversion, where optical fields interact with a nonlinear medium to generate new frequencies, is a key phenomenon in modern photonic systems. However,…
Interplay of quantum confinement and strain effects in type I to type II transition in Ge/Si core-shell nanocrystals
Ivan Marri, Stefano Ossicini, Michele Amato +2
The electronic properties of hydrogenated, spherical, Si/Ge and Ge/Si core-shell nanocrystals with a diameter ranging from 1.8 to 4.0 nm are studied within Density Functional Theor…
Pure spin current injection of single-layer monochalcogenides
Bernardo S. Mendoza, Lucila Juarez-Reyes, Benjamin M. Fregoso
We compute the spectrum of pure spin current injection in ferroelectric single-layer SnS, SnSe, GeS, and GeSe. The formalism takes into account the coherent spin dynamics of optica…
