Quantum advances rely on the production of nanoscale wires that are based on several state-of-the-art nanolithographic technologies, to develop wires via bottom-up synthesis. However, a critical challenge is to grow uniform atomic crystalline wires and construct network structures to build nanocircuits.

In a new report in Science Advances, Tomoya Asaba and a team of researchers in physics and materials science at the Kyoto University, the University of Tokyo in Japan, and the Institute of Theoretical Physics in Germany, discovered a simple method to develop atomic-scale wires in the shape of nano-rings, stripes and X-/Y- junctions.

Using pulsed-laser-deposition, the physicists and materials scientists grew single crystalline, atomic-scale wires of a Mott insulator,
