We cordially invite you to the "HZB Distinguished Lectures". Prof. Stuart Parkin from the Max Planck Institute of Microstructure Physics, Alexander von Humboldt Professor, Martin Luther University Halle-Wittenberg will present on 21 November 2016 his thoughts on "Beyond charge currents: spin and ion currents for future computing technologies".

The presentation will be given at the lecture hall of the Wilhelm-Conrad-Röntgen-Campus of HZB at 2.30 pm. After the talk we will have a get-together and time for informal discussion with "coffee and cake" in the BESSY foyer.


The era of computing technologies based on charge currents is coming to an end after more than than 40 years of exponential increases in computing power that have been largely based on shrinking devices in two dimensions. A new era of “Beyond charge!” will evolve over the next decade that will likely be based on several new concepts. Firstly, devices whose innate properties are derived not from the electron’s charge but from spin currents and from ion currents. In some cases new functionality will arise that can extend charge based devices but in other case fundamentally new computing paradigms will evolve. Secondly, devices will inevitably become three-dimensional: novel means of constructing devices, both from bottom-up and top-down, will become increasingly important. Thirdly, bio-inspired devices that may mimic the extremely energy efficient computation systems in the biological world are compelling.

In this talk on 21 November 2016 Professor Dr. Stuart Parkin will discuss possible spintronic and ionitronic devices and how they may lead to novel computing technologies.

Short biography:

Prof. Stuart Parkin’s research interests include oxide thin film heterostructures, high-temperature superconductors, and, magnetic thin film structures and spintronic materials and devices for advanced sensor, memory, and logic applications. Parkin’s discoveries in magneto-resistive thin film structures enabled a more than 1000 fold increase in the storage capacity of magnetic disk drives for which he was awarded the Millennium Technology Award from the Technology Academy Finland in 2104. Most recently, Parkin’s has proposed and demonstrated a novel storage-class memory device, "Racetrack Memory", that is an innately 3D solid-state device with the storage capacity of a disk drive but with much higher performance and reliability. Parkin’s other major research interest is cognitive - bio-inspired materials - that could enable ultra-low power computing technologies.
