The Young¿s modulus E can be estimated from the elastic deformation using Hertzian mechanics. For the quasi-one-dimensional metal tetrathiafulvalene tetracyanoquinodimethane E~20¿GPa and for the ¿ phase of the p-nitrophenyl nitronyl nitroxide radical E~2GPa. Above a few GPa, the surfaces deform plastically as evidenced by discrete discontinuities in the indentation curves associated to molecular layers being expelled by the penetrating tip.4 p.application/pdfeng(c) American Institute of Physics, 2001Pel·lícules finesMicroscòpia de força atòmicaElasticitatNanotecnologiaCristallsThin filmsAtomic force microscopyElasticityNanotechnologyCrystalsinfo:eu-repo/semantics/article5002022012-05-02info:eu-repo/semantics/openAccess
