Electron localization in periodically strained graphene
Davide Giambastiani, Francesco Colangelo, Alessandro Tredicucci +2
Pseudo-magnetic field (PMF) in deformed graphene has been proposed as a promising and flexible method to quantum-confine electronic states and create gaps in the local density of s…
Stress-strain in electron-beam activated polymeric micro-actuators
Davide Giambastiani, Fabio Dispinzeri, Francesco Colangelo +5
Actuation of thin polymeric films via electron irradiation is a promising avenue to realize devices based on strain engineered two dimensional (2D) materials. Complex strain profil…
Local tuning of WS2 photoluminescence using polymeric micro-actuators in a monolithic van der Waals heterostructure
Francesco Colangelo, Andrea Morandi, Stiven Forti +8
The control of the local strain profile in 2D materials offers an invaluable tool for tailoring the electronic and photonic properties of solid-state devices. In this paper, we dem…
Local anodic oxidation on hydrogen-intercalated graphene layers: oxide composition analysis and role of the silicon carbide substrate
Francesco Colangelo, Vincenzo Piazza, Camilla Coletti +3
We investigate nanoscale local anodic oxidation (LAO) on hydrogen-intercalated graphene grown by controlled sublimation of silicon carbide (SiC). Scanning probe microscopy (SPM) wa…
Stretching graphene using polymeric micro-muscles
Francesco Colangelo, Alessandro Pitanti, Vaidotas Mišeikis +6
The control of strain in two-dimensional materials opens exciting perspectives for the engineering of their electronic properties. While this expectation has been validated by arti…
Anisotropic straining of graphene using micropatterned SiN membranes
Fabiana Francesca Settembrini, Francesco Colangelo, Alessandro Pitanti +7
We use micro-Raman spectroscopy to study strain profiles in graphene monolayers suspended over SiN membranes micropatterned with holes of non-circular geometry. We show that a unif…
Thermal noise and optomechanical features in the emission of a membrane-coupled compound cavity laser diode
Lorenzo Baldacci, Alessandro Pitanti, Luca Masini +4
We demonstrate the use of a compound optical cavity as linear displacement detector, by measuring the thermal motion of a silicon nitride suspended membrane acting as the external…
Revealing the atomic structure of the buffer layer between SiC(0001) and epitaxial graphene
Sarah Goler, Camilla Coletti, Vincenzo Piazza +8
On the SiC(0001) surface (the silicon face of SiC), epitaxial graphene is obtained by sublimation of Si from the substrate. The graphene film is separated from the bulk by a carbon…
