The effect of coating in increasing the critical size of islands on a compliant substrate
نویسندگان
چکیده
A flexible electronic system may consist of a polymeric substrate and an array of stiff islands, on which devices are fabricated. When the substrate is stretched, the devices on the islands experience small strains but the islands may debond if they exceed a critical size. The authors show that a thin layer of polymer coating, covering the islands and the substrate, can markedly increase the critical island size. © 2007 American Institute of Physics.

EFFECT OF SUBSTRATE TEXTURE AND DEPOSITION CURRENT DENSITY ON PROPERTIES OF NiNANOCRYSTALLINE ELECTRODEPOSITS
Abstract: Nickel was electrodeposited onto copper substrates with high {111} and {400} peak intensities. The grain size of coatings deposited onto the copper substrate with a higher {111} peak intensity was finer. Spheroidized pyramid morphology was obtained at low current densities on both copper substrates. By increasing the deposition current density, grain size of the coating was increased ...
