ABSTRACTNanosecond structural changes in a crystal lattice during pulsed laser annealing have been measured using time-resolved Low Energy Electron Diffraction (LEED). LEED is both structure and surface (∼ 10Å) sensitive. Lattice temperatures can be extracted from Debye-Waller like extinction coefficients. Combining these with nanosecond time resolution provides a surface probe for short-time dynamical processes. The technique is used to observe the time evolution of a Ge(l11) surface during pulsed laser annealing. The results demonstrate rapid formation of a liquid layer and subsequent surface recrystallization and cooling.

The wave guiding feature of the optical fibre optical fibres is specifically exploited to construct a novel type of electron gun to realize single-shot low-energy electron diffraction experiments with the sub-picosecond resolution for studying irreversible samples.
