  • The formation of Au nano particles from thin films on patterned substrates depends sensitively on film thickness and time. The nano Au line and shape formed by annealing Au films on patterned oxide substrates are different from those formed on semiconductor. In this experiment, we deposited thin Au films on patterned $Al_2O_3$(0006) using E-beam evaporator, and annealed them at various temperatures and thickness under various conditions by RTA. We measured behavior of the Au during annealing Au structure and shape are changed when Au film becomes thicker. The shape of the resultant Au nano particles and their coarsening process are investigated using SEM and XRD.

  • Soft and stretchable electronics, equipped with diverse functional devices, have recently garnered attention owing to their versatility in applications such as stretchable displays, flexible batteries, and electronic skin (e-skin). A fundamental challenge in realizing stretchable electronics lies in conferring the necessary flexibility to crucial electrical components such as electrodes and devices. However, the prevalent electronic materials, exhibit limited stretchability, presenting a significant obstacle to the advancement of soft and stretchable electronics. To overcome this challenge, various strategies rooted in geometrical engineering have been explored to enhance the adaptability of rigid materials. This study delves into the realm of geometrical engineering by, examining techniques such as serpentine patterns, kirigami-inspired designs, and island structures, with a keen focus on recent progress and future prospects.
