Abstract
The dynamics of STM based hydrogen desorption at silicon surfaces is another process in which an open systems approach is appropriate. Therefore, we adopt a master equation model previously applied to this problem, and propose resonant IR overtone excitation of the surface Si-H vibration as a method for enhancing desorption rates. Finally, we present findings of our experimental efforts at implementing this proposal thus far.
