University of Twente invites you to their event

MESA+ Colloquium - June 2021

About this event

From 2021 onwards a new MESA+ colloquium series will start. These colloquia will take place eight times a year on the first Monday of the month (except January, July, August and December) from 16.00 - 17.00 hrs. Initially this will be an online event.

The fifth colloquium takes place on June 7, 2021. Please note that this time the colloquium will start at 17.00 hrs. instead of 16.00 hrs. Our guest speaker is Prof. Beatriz Noheda of University of Groningen (Groningen, The Netherlands). The title of her talk is 'The matter of future computers: complex oxides for synaptic devices'.

Hosted by the MESA+ Piezo electronic materials groups.

Abstract

The matter of future computers: complex oxides for synaptic devices

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. Also recent is the realization that transistors and standard circuit elements will not allow sufficient progress in this direction. It is now clear that the quest for low-power cognitive computing needs 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. The focus will be on complex oxides, as they often display multiple nearly-degenerate states among which the system can transition with very small changes of external stimuli, therefore, offering excellent basis to achieve large responses with low driving voltages. In addition, their sensitivity to composition or strain, allows engineering of a very diverse set of functionalities by purposeful synthesis of thin layers or heterostructures, which nowadays is possible down to the atomic control. Emphasis will be made on new materials developments, such as the novel nanoscale ferroelectrics based on HfO2, as well as on materials that self-assemble in organized networks forming nanoscale conduction paths, such as thin films with ferroelastic, nanometer-size domains or polymer-assisted templating of complex oxides.
