Conventional multi-scale array fabrication techniques are facing challenges in reconciling the contradiction between better device performance and lowering the fabrication cost and/or energy consumption. A team of researchers in the US (North Carolina State University, Iowa State University) used facile mixed-metal array fabrication method based on guided self-assembly of polymerizing organometallic adducts derived from the passivating oxides of a ternary liquid metal, to create mixed metal wires. They fabricated large-area, high-quality organometallic nano- to micro-wire arrays without compromising wire continuity or array periodicity. Using capillary bridges on a preceding layer, they made hierarchical arrays with complex geometries. They observed guided mode resonance while their complex band structures enabled fabrication of diodes or gates. According to the researchers their work demonstrates a simple, affordable approach to opto-electronics based on self-assembling arrays… read more. Open Access TECHNICAL ARTICLE
