Abstract

Dynamical characteristics of laser desorption and chemical processes in Group IV elements have been investigated by means of space/time resolved optical spectrometry in micrometers and nanoseconds scale on the light emitted from desorbed particles. The results suggest that desorbed atoms are coagulated in the form of large size clusters in a few ns after laser excitation. These clusters subsequently decompose into their ultimate forms of monomers. This interpretation is consistent with the conclusion drawn from our time-of-flight analysis of decomposition in 100 ns time scale.
