Smallest logic circuit fabricated with single-electron transistors

(Phys.org)—In order to meet the growing demand for small-scale, low-power computing, researchers have been aggressively downscaling silicon-based computing components. These components include transistors and logic circuits, both of which are used to process data in electronic devices by controlling voltage. However, the smallest type of logic circuit, called a half-adder, has not yet been fabricated on as small a scale as it could be.
