The increasing demand for energy-efficient products gave rise to electronic fabs looking for new green manufacturing processes. Bottom-up techniques have the potential to reduce economic and environmental costs due to implementing low-dimensional materials with unique properties.
We demonstrated the formation of low-dimensional metallic nanostructures based on the DNA origami technique, which can be considered as building blocks for electronic circuits. DNA templates are used as molds to guide the placement and growth of the metallic 1D nanowires. This solution-based and high-resolution nanofabrication technique complements other nanolithography techniques such as electron-beam lithography and thermal scanning probe lithography. Thus, the shape of the nanostructures can be controlled and measured.
Electronic transport on these assemblies is non-ohmic and deteriorates at low temperatures. Temperature-dependent charge transport measurements reveal the dominating mechanisms along these wires.
