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…
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…
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…
