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 sp 3 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 sp 2 carbons is varied in an sp 3 network. The dependence of the average coordination number as well as the sp 3/sp 2 atom ratio on the atom fraction of hydrogen has been investigated in light of the random covalent network model.
