Structure and dynamics of ${\mathrm{C}}_{60}$ and ${\mathrm{C}}_{70}$ from tight-binding molecular dynamics

Structural and vibrational properties of ${\mathrm{C}}_{60}$ and ${\mathrm{C}}_{70}$ fullerenes are studied by molecular dynamics using a recently developed tight-binding potential model. It is shown that this tight-binding molecular-dynamics scheme has accuracy comparable to ab initio techniques and is very efficient for studying the finite temperature properties of fullerenes.
