Their size can be controlled by thermal treatment, reaching tens of nanometers laterally and height of 1.5 nm upon annealing at 1080 °C. Ab initio calculations show that Ar nanobubbles are subject to pressures reaching tens of GPa, their formation being driven by minimization of the energy cost of film distortion and loss of adhesion. 2015-09-09 00:00:00 irradiation ten graphene membrane evidence film distortion Ar nanobubbles Ab initio calculations show subject 1.5 nm energy cost minimization GPa Pressure nanometers laterally formation adhesion Nanobubble Ir annealing GrapheneWe
