Abstract
The influence of hydrogen on the structure and properties of tetrahedral am orphous carbon (ta-C) is studied by tight-binding molecular-dynamics simula tions. The results show that hydrogen tends to break carbon-carbon bands in ta-C. Reduction of C-C coordinations makes ta-C softer and introduces more electronic states in the energy-gap region, [S0163-1829(98)00945-X].
