Ionic Liquid and Amorphous Metal-Oxide Semiconductor Interactions: Towards a New Programmable Neuromorphic Platform

Neuromorphic computing attempts to model neuro-biological architectures using analog electronic signals.  One emerging concept for neuromorphic computing involves ionic-liquid gated oxide materials.  In this poster we will overview our group’s recent research investigating ionic liquid-amorphous metal oxide semiconductor interactions.  Finally, we will overview a new large scale programmable neuromorphic computing concept, which combines ionic liquid electrowetting and ionic liquid control of a materials transport.  We will show, that using a hydrated ionic liquid (BMIM-TFSI), we can control the threshold voltage and on-current of an amorphous metal oxide transistor via H+ injection. Agile ionic liquid electrowetting fluid transport will also be demonstrated.  Combining the electronic transport control and the pixelated electrowetting array results in a programmable neuromorphic platform that can be scaled to high pixel counts.
