Reaction Kinetics on Diamond: Measurement of HI Atom Destruction Rates

  • Stephen J. Harris (a1) and Anita M. Weiner (a1)


We describe the first measurements of reaction kinetics between diamond and a gas phase species—H atoms—involved in its formation. We develop a remarkably simple method to measure H atom concentrations and use the method to measure γd, the destruction probability of H atoms on diamond at 20 torr and 1200 K. We find γd = 0.12. This value is close to that estimated from gas phase alkane rate constants.
