Nanomaterials: Pillars of the assembly

The ever-increasing demand for enhanced performance in electronic devices such as solar cells, sensors and batteries is matched by a need to find ways to make smaller electrical components. Several techniques have been proposed for creating tiny, nanoscale structures on silicon, but these types of ‘nanopatterning’ tend to involve low-throughput, high-cost approaches not suited to large-scale production. Sivashankar Krishnamoorthy and co-workers at the A*STAR Institute of Materials Research and Engineering have now found a simple and robust method for nanopatterning the entire surface of a silicon wafer.
