Azo-polymer thin films exhibit a unique surface morphology under light irradiation due to the photoisomerization reaction. The morphology can be manipulated by controlling light properties such as polarization. Here, we demonstrate in-situ direct observation of the formation of the surface morphology on the azo-polymer film using high-speed atomic force microscopy. The change in surface morphology was precisely investigated in real time at the nanoscale.
