ICN2 seminar by Beatriz Noheda: "The matter of future computers: oxide thin films for neuromorphic devices''

Abstract: Although neuromorphic computing concepts have been put forward half a century ago, the urgency for low power solutions that can handle big data efficiently, is a recent development. So far cognitive/brain-inspired computing is the only paradigm that can foresee energy savings of several orders of magnitude. However, to get there requires a huge multidisciplinary effort and a holistic approach that starts with the use of materials with intrinsic plasticity. Here I will highlight how the latest progress in materials science can offer promising alternatives for future cognitive devices giving examples from the research of my own group. In particular, I will present work on memristive devices with transition metal oxides, such as nickelates and manganites, as well as with novel nanoscale ferroelectrics based on HfO2.
