We report a strain-induced direct-to-indirect band gap transition in mechanically deformed
WS 2 monolayers (MLs). The necessary amount of strain is attained by proton irradiation of …

At the few‐atom‐thick limit, transition‐metal dichalcogenides (TMDs) exhibit strongly
interconnected structural and optoelectronic properties. The possibility to tailor the latter by …

Thanks to their peculiar shape and dimensions, semiconductor nanowires (NWs) are
emerging as building components of novel devices. The presence of wurtzite (WZ) phase in …

We performed an experimental study of coupled optical cavity arrays in a photonic crystal
platform. We find that the coupling between the cavities is significantly larger than the …

Many of the most advanced applications of semiconductor quantum dots (QDs) in quantum
information technology require a fine control of the QDs' position and confinement potential …

We investigate the effect of large in-plane strain and vertical electric fields on the binding
energies of excitonic complexes confined in single InGaAs/GaAs quantum dots (QDs) and …

We review an innovative approach for the fabrication of site-controlled quantum emitters (ie,
single-photon emitting quantum dots) based on the spatially selective incorporation and/or …

The fabrication of integrated quantum dot (QD)-optical microcavity systems is a requisite
step for the realization of a wide range of nanophotonic experiments (and applications) that …

We demonstrate triggered single-photon emission from a novel system of site-controlled
quantum dots (QDs), fabricated by exploiting the hydrogen-assisted, spatially selective …

Remarkable improvements in the magneto-optical properties of Zn1− xCoxO thin films were
achieved by post-growth hydrogen irradiation at temperatures of 400° C. Hydrogen …
