ANALYTICAL EXPRESSIONS FOR BULK MODULI AND FREQUENCIES OF VOLUMETRICAL VIBRATIONS OF FULLERENES C20 AND C60
Аннотация:
In the present paper simple analytical expressions connecting bulk moduli for fullerenes C20 and C60 with stiffness of interatomic bond and geometrical characteristics of the fullerenes are derived. Ambiguities related to definition of the bulk modulusare discussed. Nonlinearvolumetricaldeformationof the fullerenesis considered. Pressure-volume dependence for the fullerenes under volumetrical compression are derived. Simple analytical model for volumetrical vibrations of the fullerenes is proposed. The expression connecting frequencies of volumetrical vibrations for fullerenes C20 and C60 with parameters of interatomic interactions are obtained.
