DIAMOND-GRAPHITE HYBRIDS AND THE NATURE OF AMORPHOUS-CARBON AND DIAMOND-LIKE CARBON

The nature of amorphous carbon has been explored by molecular mechanic s by examining the structures of species such as C84Hx and C150Hx, whe rein the percentage of sp(3) carbons is progressively increased in a g raphitic network. The nature of diamond-like carbon has been similarly investigated by examining the structures of C84Hx and C102Hx where th e percentage of sp(2) carbons is varied in an sp(3) network. The depen dence of the average coordination number as well as the sp(3)/sp(2) at om ratio on the atom fraction of hydrogen has been investigated in lig ht of the random covalent network model.
