Effect of Tensile Strain and Gold Thickness on the Micropattern Topography of Gold Thin Coatings Deposited on Polydimethylsiloxane
Abstract: The polydimethylsiloxane (PDMS) film was applied a tensile strain, next the following steps was should be done: fixing the tensile strain, sputtering the gold film on the surface of PDMS film, and then releasing the tensile strain, a large-scale area ripple structure was formed. The ripple dislocations, the cracks and the oriented surface cracks appeared simultaneously during the forming of the ripple structure. This study also discussed the wavelengths of ripple structures resulted from the amount of tensile strain (30%, 50%, 70%, 90% and 110%) and gold thickness (4Å and 10Å). The wavelengths of ripple structures decreased as the tensile strains increased and gold thickness decreased.
