An atomic switch is a nanoionic device that controls the diffusion of metal ions and their reduction/oxidation processes in the switching operation to form/annihilate a metal atomic bridge, which is a conductive path between two electrodes in an ON-state. Since metal atoms can provide a highly conductive channel even if their size is in the nanometer scale, atomic switches may enable downscaling to...
A combinatorial synthesis and high throughput characterization was employed to accelerate the new materials exploration. Also tow basic guide lines were shown to design the future nano CMOS. They are amorphous structure and defect control. As examples, we examined a HfO2-Y2O3-Al2O3 ternary oxide for gate oxide and Pt-W, Ru-Mo amorphous metals for metal gate. Moreover, C-incorporation is effective...
We propose a three-terminal solid-electrolyte nanometer switch, where the control gate is separated from the current path. This novel switch resolves the issues arising from large current during switching (>1mA) in a two-terminal solid-electrolyte switch. We demonstrate that the drain current reversibly switches when a metallic bridge electrochemically forms or dissolves between the source and...
