Abstract

The nature of amorphous carbon has been explored by molecular mechanics by examining the structures of species such as C84Hx and C150Hx, wherein the percentage of sp3 carbons is progressively increased in a graphitic network. The nature of diamond-like carbon has been similarly investigated by examining the structures of C84Hx and C102Hx where the percentage of sp2 carbons is varied in an sp3 network. The dependence of the average coordination number as well as the sp3/sp2 atom ratio on the atom fraction of hydrogen has been investigated in light of the random covalent network model.
