Abstract:Nanoengineering polar oxide films have attracted great attention in energy storage due to their high energy density. However, most of them are deposited on thick and rigid substrates, which is not conducive to the integration of capacitors and applications in flexible electronics. Here, an alternative strategy using van der Waals epitaxial oxide dielectrics on ultra‐thin flexible mica substrates is developed and increased the disorder within the system through high laser flux. The introduction of defects can e… Show more
