Ultrafast high energy electron diffraction in reflection geometry is employed to study the structural dynamics of self-organized Germanium hut-. dome-. and relaxed clusters on Si(001) upon femtosecond laser excitation. Utilizing the difference in size and strain state the response of hut- and dome clusters can be distinguished by a transient spot profile analysis. https://www.bekindtopets.com/super-value-Keychron-M4-Wireless-4K-Mouse-flash-choice/
