Fabrication and temperature-dependent electrical characterization of a C-shape nanowire patterned by a DNA origami

Abstract We introduce a method based on directed molecular self-assembly to manufacture and electrically characterise C-shape gold nanowires which clearly deviate from typical linear shape due to the design of the template guiding the assembly. To this end, gold nanoparticles are arranged in the des...
