Abstract

original image

Room temperature single-electron transistor core nanostructures are fabricated on a large scale with DNA origami as a template with an unprecedented yield. The accuracy of DNA origami enables precise positioning of a Coulomb island in the center of a 10 nm gap between the source and the drain electrodes, which can not be realized by using state-of-the-art nanofabrication techniques.
