Background
Thermal compression creates wavy and herringbone wrinkles in a thin amorphous-silicon film on soft silicone rubber. The study examines the height and spacing of these wrinkles to understand how the film deforms.
What the study found
Thermal compression creates wavy and herringbone wrinkles in amorphous silicon films on PDMS, an elastic polymer.
The study compares wrinkle amplitude and wavelength with a deformation model developed for crystalline silicon.
Questions and limits
Control over wrinkle shape does not establish that an electrical connection survives repeated deformation.
How to compare the results
Compare film thickness and modulus, prestrain, measurement location, and bonding to the substrate.
