Self-assembly, autonomous organization of materials into hierarchical structures, offers a unique bottom-up approach for the controlled fabrication of electronic components. Potentially, self-assembled low-dimensional materials could be integrated into functional architectures without the need of expensive cleanroom tools and facilities.
Here we report a study on the electrical characterization of quasi-1D metallic nanostructures using two biotemplates. The first employs the DNA origami technique, while the second utilizes the microtubule lumen for growth. In both cases, metallic seed nanoparticles are bound to the template and reduced forming a continuous nanowire. Thus, the shape and length of the wire can be controlled. The electrical characterization data shows two kinds of transport behaviours: linear and non-linear current-versus-voltage responses, depending on the continuity of the metal nanowires. Temperature-dependent charge transport measurements reveal the dominating mechanisms along these wires, offering an insight into the reliability for this cost-effective electronic device fabrication.
