However, the influence of strain on key electronic characteristics such as conductivity and work function has not yet been elucidated. Here, we present a combined experimental and computational study of surface electronics on thin crystals of molybdenum carbide (Mo2C). Conductive atomic force microscopy (C-AFM) and Kelvin probe force microscopy (KPFM) performed on rippled regions of crystal surfaces reveal a significant increase in electrical conductivity and a notable reduction in work function under tensile strains of 1% and below. Ab initio calculations confirm the trends observed in the experiments, pointing toward increased density of states (DOS), enhanced mobility, and reduced work function under tensile strain. Our work highlights the potential of strain engineering for tuning the electronic characteristics of thin TMCs.eninfo:eu-repo/semantics/closedAccessAtomic Force MicroscopyConductivityStrainSurface ElectronicsTransition Metal CarbidesWork FunctionArticle2-s2.0-10501891941210.1021/acsanm.5c03237
