The research describes the development of an ultrathin and uniform wafer-sized van der Waals ferroelectric oxide. The material was synthesized at atomic-level thickness using graphene-inspired methods and transfer to various substrates. Continuous structures with a low surface resistance of around 10 Ω/sq and a high transparency of around 80% were achieved. The technology includes physical depositions, delamination and film transfer, enabling large-scale production. These properties open up possibilities for flexible transparent electrodes in photonics and optoelectronics. The study demonstrates applications such as smart contact lenses and thermal camouflage. The process is transferable to various quasi-2D materials and changes the paradigm in the field of 2D crystals.[1][5]
