Strain-tuning of the electronic, optical, and vibrational properties of two-dimensional crystals The variegated family of two-dimensional (2D) crystals has developed rapidly since the isolation of its forerunner: Graphene. Their plane-confined nature is typically associated with exceptional an...

Our recent work on a novel, very stable and bright perovskite with interesting optoelectronic properties.

Brightly Luminescent and Moisture Tolerant Phenyl Viologen Lead Iodide Perovskites for Light Emission Applications Lead halide perovskites are outstanding materials for optoelectronics, but they typically feature low stability against external agents. To overcome this drawback, LHPs based on quaternary ammonium cations, such as phenyl viologen lead iodide (PhVPI), were found to be promising candidates, being wat...

Our recent work where we discuss innovative approaches for the formation of site-controlled quantum dots and nanowires, by playing with the effect of hydrogen in dilute nitrides

Tailoring the optical properties of dilute nitride semiconductors at the nanometer scale - IOPscience Published 12 February 2021 • © 2021 IOP Publishing Ltd Nanotechnology, Volume 32, Number 18 Citation Giorgio Pettinari et al 2021 Nanotechnology 32 185301

Here we perform nanoindentation experiments in mechanically-deformed two-dimensional materials and present a method to determine their elastic properties

Nanoscale Measurements of Elastic Properties and Hydrostatic Pressure in H2‐Bulged MoS2 Membranes A detailed study of elastic and thermodynamic properties of nanoblisters, made on purpose in MoS2 bulk flakes by means of low‐energy proton irradiation, is provided. An experimental approach, based o...

Achieving giant strains (~14%) in ordered arrays of domes made of two-dimensional materials

Engineered Creation of Periodic Giant, Nonuniform Strains in MoS2 Monolayers Spherically shaped 2D membranes are created via hydrogen irradiation of bulk MoS2. Here, a novel engineering protocol is developed to tailor the size, shape, and position of the bulges. Periodic, non...

Creating hydrogen-filled domes made of two-dimensional materials at the nano-/micro-scale :-)

Controlled Micro/Nanodome Formation in Proton‐Irradiated Bulk Transition‐Metal Dichalcogenides Proton irradiation of bulk transition‐metal dichalcogenides leads to the blistering of atomically thin domes filled with hydrogen. The domes stud the crystal surface and locally turn the dark bulk ma...
