The continuous miniaturization of electronics is nearing an end due to physical constraints. Novel materials systems and device concepts are needed to create next generation electronics that are more powerful, but requires less energy. Two-dimensional (2D) materials are molecularly thin, layered materials that have great potential in energy-efficient electronics and photonics. Iontronics is a newly emerging, interdisciplinary concept that bridges electronics, ionics, solid-state physics and biological science. An iontronic device has electronic properties or functions controlled by ionic motion and arrangement. I will describe some of our work in the Nanoionics and Electronics Lab using ions to control transport in 2D materials for applications such as neuromorphic computing (e.g. iontronic artificial synapses). I will also discuss some results on the direct-writing of silver nanofilaments in ionic liquid-filled solid polymer electrolytes to achieve multiple distinguishable resistance states, which could be useful for artificial neural networks.
