Atomic Switch: Atom/Ion Movement Controlled Devices for Beyond Von‐Neumann Computers
説明
<jats:title>Abstract</jats:title><jats:p>An atomic switch is a nanoionic device that controls the diffusion of metal ions/atoms and their reduction/oxidation processes in the switching operation to form/annihilate a conductive path. Since metal atoms can provide a highly conductive channel even if their cluster size is in the nanometer scale, atomic switches may enable downscaling to smaller than the 11 nm technology node, which is a great challenge for semiconductor devices. Atomic switches also possess novel characteristics, such as high on/off ratios, very low power consumption and non‐volatility. The unique operating mechanisms of these devices have enabled the development of various types of atomic switch, such as gap‐type and gapless‐type two‐terminal atomic switches and three‐terminal atomic switches. Novel functions, such as selective volatile/nonvolatile, synaptic, memristive, and photo‐assisted operations have been demonstrated. Such atomic switch characteristics can not only improve the performance of present‐day electronic systems, but also enable development of new types of electronic systems, such as beyond von‐ Neumann computers.</jats:p>
