Slow dynamics in an azopolymer molecular layer studied by x-ray photon correlation spectroscopy.

Abstract

We report the results of x-ray photon correlation spectroscopy (XPCS) experiments on multilayers of a photosensitive azo-polymer which can be softened by photoisomerization. Time correlation functions have been measured at different temperatures and momentum transfers (q) and under different illumination conditions (dark, UV or visible). The correlation… (More)
