Following the success of the first, second, third and fourth OTF conferences in Chicago, Cancun, Rome & Portugal which took place in July 2014, March 2015, July 2017 and July 2019, we are delighted to be organising a fifth series. Complex oxide thin films are finding applications in a wide range of energy and information technologies, including electron and ion conductors, photovoltaics, thermoelectrics, dielectrics, and resistive switching. Irrespective of whether single thin films or more sophisticated multilayered systems are employed, each of these technologies requires a thorough knowledge of the oxide physicochemical properties, its interactions with the environment and the role of defect/interface/boundary effects that might stem between film and substrate, layers with different compositions or even simply from the grain boundaries. Whilst depending on the technology area the key properties might be different, many of the materials optimization strategies may be common. Therefore, we believe that the discussion between diverse and even complementary researchers’ communities can be extremely beneficial for a better understanding of the crucial aspects that need to be addressed to improve materials properties. The purpose of this meeting is hence to foster the exchange of ideas between the relevant energy and information themes with the overall aim of sparking extensive discussions of the advances that materials physics and chemistry can make in thin film applications. Key Sessions* Thin film synthesis and growth, defect, disorder in oxide films and heterostructures Physics, energy conversion and storage using oxide thin films Field effect and electronic devices Advanced characterization approaches Emerging phenomena and applications of novel material system Two-dimensional electronic transport and magnetism at oxide interfaces *Subject to change Student Offer Take advantage of this fantastic opportunity for students!
