## Description

- description: A proper understanding of the molecular transport occurring in the
    near-surface region is a crucial prerequisite for the successful application of
    amorphous chalcogenides. This study provides information on the surface pattern
    decay in bulk samples and thin films of amorphous As20Se80. Single-period sinusoidal
    gratings were embossed into the sample surfaces, and subsequent annealing-induced
    decay or flattening of the surface grating was analyzed to obtain the rate constant
    of the process. The studies were performed in bulk samples, thermally evaporated
    thin films, and, for the first time, in solution processed chalcogenide thin films
    prepared by spin-coating. The obtained data provide a comparison of near-surface
    molecular transport in the As20Se80 amorphous material prepared by different methods.
