Comparative study of compression in fullerites and carbon nanotubes under high pressure

M.Goyal, B.R.K.Gupta

In the present study, an analysis of high pressure compression in fullerites such as C60, C70,C84 and Carbon nanotubes has been performed using the two parameter based isothermal equations of state,i.e.Murnaghan equation, Kumar equation,Vinet equation, Suzuki equation, Sharma equation and usual TaitÂ’s equation. The results achieved from these equations are compared with the available experimental data. It is found that the results obtained from usual TaitÂ’s equation of state are in close agreement with the experimental data as compared to those calculated from other equations of state. A good agreement between theory and experiment demonstrates the validity of the TaitÂ’s equation of state in nanostructured fullerites and nanomaterials as in case of bulk materials.
