The in-plane stiffness and Poisson’s ratio values are found to be smaller than those of graphene, and its yielding strain decreases in the presence of various vacancy defects and also at high ambient temperature. We also found that the band gap can be strongly modified by applied strain in the elastic range.EnglishAmbient temperaturesApplied strainBand gapsElastic propertiesElastic rangesElastic strainFirst-principles calculationIn-plane stiffnessMechanical and electronic propertiesPoisson's ratioVacancy DefectsElectronic propertiesHydrocarbonsMonolayersPoisson ratioVacanciesMechanical propertiesArticle10.1063/1.3353968
