Dark exciton signatures in the infrared transient absorption of MoS monolayer
Tian-Xiang Qian, Marco D'Alessandro, Claudio Attaccalite +3
Dark excitons play a central role in the nonequilibrium dynamics of two-dimensional semiconductors, but remain difficult to characterize. Transient-absorption experiments, with pro…
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…
Real-time ab initio description of the photon-echo mechanisms in extended systems: the case study of bulk GaAs
M. D'Alessandro, D. Sangalli
In this paper we present an ab initio real-time analysis of free polarization decay and photon echo in extended systems. As a prototype material, we study bulk GaAs driven by ultra…
Work function, deformation potential, and collapse of Landau levels in strained graphene and silicene
D. Grassano, M. D'Alessandro, O. Pulci +3
We perform a systematic {\it ab initio} study of the work function and its uniform strain dependence for graphene and silicene for both tensile and compressive strains. The Poisson…
