    Talk Title: Novel Memristive Oxides and Devices for Neuromorphic Data Computing with Dual Functions to Sense for Chemical Species or Integrate Batteries

    Abstract: The next generation of information memories and neuromorphic computer logics in electronics rely largely on solving fundamental questions of mass and charge transport of ionic defects in materials and their structures. Through this presentation we introduce the concept of memristors to store data and information based on ionic carriers for Resistive Random Access Memories and Neuromorphic Computing beyond classic electronic transistors. Understanding the defect kinetics in the solid state material building blocks and their interfaces with respect to lattice, charge carrier types and interfacial strains are the prerequisite to design new material memristive architectures and device structures.

    Through this presentation basic theory1 and model experiments for solid state oxides their impedances and memristance2, electro-chemo-mechanics and lattice strain3-5 modulations is being discussed as a new route for tuning material and properties in ionic conducting oxide film structures up to new device prototypes based on resistive switching. Central are the making of new oxide film materials components, and manipulation of the charge carrier transfer and defect chemistry (based on ionic, electronic and protonic carriers)1-2, 5-6, which alter directly the resistive switching property and future computing performances. A careful study on the influence of microstructure and defect states vs. the materials` diffusion characteristics is in focus. For this, we suggest novel oxide heterostructure building blocks and show in-situ spectroscopic and microscopic techniques coupled with electrochemical micro-measurements to probe near order structural bond strength changes relative to ionic, protonic and electronic diffusion kinetics and the materials integration to new optimized device architectures and computing operation schemes. In addition, new perspectives in the field from the materials science point view will be introduced by demonstrating first strained memristors to tune performance beyond extrinsic doping or even radically suggesting to select Li as a moving cation for memristive switches connecting classic solid-state Li conductors employed in batteries8-10 to novel lithium-operated memristive computational devices.

    At the end, the talk is set to dream out loud a little what happens if we functionalize electrochemical devices and oxide hardware to gain multiple functionalities: memristors that can also have dual functions such as to not only compute data neuromorphically but also track the environment and sense for chemical species, or also have integrated battery functions?

    Bio: Jennifer Rupp is the Thomas Lord Assistant Professor of Electrochemical Materials at the Department of Materials Science and Engineering, and Assistant Professor at the Department of Electrical Engineering and Computer Science at MIT. Prior she is a non-tenure track assistant professor at ETH Zurich Switzerland where she was holding two prestigeous externally funded career grants, namely an ERC Starting Grant (SNSF) and Swiss National Science Foundation (SNF) professorship from 2012 on.
    She previously was affiliated as a visiting and senior scientist at the MIT (2012-2011), the National Institute of Materials Science (NIMS) in Tsukuba Japan (2011), and was working as a postdoc at ETH Zurich (2010-2006). Rupp team`s current research interests are on solid state material design and tuning of structure-property relations for novel energy and information devices and operation schemes. This ranges from alternative energy storage via solid state batteries or catalytic convertor systems processing by smart material design solar light and CO2 to renewable synthetic fuels, or novel types of neuromorphic memories and computing logic entities for data storage and transfer beyond transistors. Here, her team goes the whole way from material design, novel processing techniques to make ceramics, cermets or glassy-type ceramic structures up to device prototypes, their operation and characteristics. She has published more than 80 papers, invented 9 patents, and enjoys to be active discussing material tech trends on the theme of energy with the public, economists and policy makers being a frequent speaker and member of the World Economic Forum (2015-2018). Rupp and team received several honors and awards such as 2017 Science Electrochemistry Award by Volkswagen and BASF, keynote lecture at Nature Energy conference 2016, "Top 40 international scientist under the age of 40" by World Economic Forum 2015, Spark Award for the most innovative and economically important invention of the year 2014 at ETH Zurich, Gordon Research lecture 2014, the Kepler award “new materials in energy technology” by the European Academy of Science 2012 or Young Scientist Award by the Solid State Ionic Society.
