제목 DNA nanowire array-enabled lithography for electronic devices
초록 DNA molecules have been widely recognized as promising building blocks for constructing functional nanostructures with two main features: self-assembly and rich chemical functionality. The intrinsic feature size of DNA makes it attractive for creating versatile nanostructures. Here, highly aligned DNA nanowire arrays were crafted by flow-assisted self-assembly of a drop of DNA aqueous solution on a flat polymer substrate. Subsequently, they were exploited as “ink” and transfer-printed on chemical vapor deposited (CVD)-grown graphene substrate. The oriented DNA nanowires served as the lithographic resist for selective removal of graphene, forming highly aligned graphene nanoribbons to render the fabrication of field-effect transistors. In addition, by subjecting the solution composed of the complex of DNA and a positively charged conjugated polymer in sphere-on-flat geometry, highly ordered DNA patterns were formed and utilized as templates to fabricate two terminal device arrays.
