## Description

- description: "The realization of ordered strain fields in two-dimensional crystals
    is an intriguing\r\nperspective in many respects, including the instauration of
    novel transport regimes and the\r\nachievement of enhanced device performances.
    However, the current straining techniques\r\nhardly allow to reach strain values
    higher than 2-3 % and in most cases there’s no control\r\nover the strain distribution.
    In this work, we demonstrate a method to subject micrometric\r\nregions of atomically-thin
    molybdenum disulphide (MoS2) to giant strains with the desired\r\nordering. Selective
    proton-irradiation of bulk flakes had been proposed to create arrays of\r\nsize/position
    controlled monolayer domes containing pressurized hydrogen. However, therein\r\nthe
    gas pressure is ruled by energy minimization, which limits the extent and geometry
    of the\r\nmechanical deformation of the 2D membrane. Here, we develop a protocol
    to create a\r\nmechanical constraint, and atomic force microscopy measurements
    reveal that this constraint\r\nalters remarkably the morphology of the domes,
    otherwise subject to universal scaling laws.\r\nThis enables the realization of
    unprecedented periodic configurations of large strain gradients\r\n-estimated
    by numerical simulations- with the highest strains being close to the rupture\r\ncritical
    values (> 10 %). The creation of such high strains is confirmed by Raman\r\nexperiments.
    The method proposed here represents an important step towards the strain\r\nengineering
    of two-dimensional crystals."
