Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Large‐scale fabrication of room‐temperature single‐electron transistors core nanostructures in an unprecedented yield is achieved by using DNA self‐assembly strategy, in which three gold nanorods (13 nm × 38 nm) are precisely positioned on the DNA origami surface as source, drain, and gate electrodes, with the distance between the source and drain electrodes smaller than 10 nm. As reported <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">on page 3567</ext-link> by Q. Wang and co‐workers, a gold nanoparticle (4.5 nm) can be located in the center of the source and drain electrodes as Coulomb island. This delicate nanostructure cannot be achieved using state‐of‐art nanofabrication techniques. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t8d8cpr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
