Optical properties of hydrogenated graphene superlattices
Vasil A. Saroka, Olivia Pulci, Marco D'Alessandro
We investigate with first principles theoretical methods optical response accounting for excitonic effects of quasi-one dimensional monolithic arrays of graphene nanostripes -- two…
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,…
Transitions in Xenes between excitonic, topological and trivial insulator phases: influence of screening, band dispersion and external electric field
Olivia Pulci, Paola Gori, Davide Grassano +2
Using a variational approach, the binding energies of the lowest bound excitons in Xenes under varying electric field are investigated. The internal exciton motion is describ…
Interlayer and intralayer excitons in AlN/WS heterostructure
C. Attaccalite, M. S. Prete, M. Palummo +1
Transition metal dichalcogenides (TMD) monolayers, holding potential as good sunlight absorbers, are promising materials for next-generation optoelectronic devices. They may enable…
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…
Tuning the doping of epitaxial graphene on a conventional semiconductor via substrate surface reconstruction
Miriam Galbiati, Luca Persichetti, Paola Gori +8
Combining scanning tunneling microscopy and angle-resolved photoemission spectroscopy, we demonstrate how to tune the doping of epitaxial graphene from p to n by exploiting the str…
