In situ fragmentation of Al/Al2O3 multilayers on flexible substrates in biaxial tension

Interface fails and Young’s module approximation of multilayer flexible devices through finite element method

“…Comparing results with Putz et al [ 33 ], brittle cracking on crystalline oxide layers, such as ITO, can be enhanced if its thickness decreases. So, a reciprocation was found between the rapid rises of the strain energy dissipation for layers with high Young's module, even if several are brittle, and the displaying of failures between and throughout the layers.…”
