Novel bio-inspired method to grow high-quality graphene for high-end electronic devices

Drawing inspiration from how beetles and tree frogs keep their feet attached to submerged leaves, the study breaks current technology bottleneck and enables wide ranging applications for graphene

A team of researchers from the National University of Singapore (NUS), led by Professor Loh Kian Ping, who heads the Department of Chemistry at the NUS Faculty of Science, has successfully developed an innovative one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates, opening up opportunities for graphene to be used in high-value applications that are currently not technologically feasible.

This breakthrough, inspired by how beetles and tree frogs keep their feet attached to submerged leaves, is the first published technique that accomplishes both the growth and transfer steps of graphene on a silicon wafer. This technique enables the technological application of graphene in photonics and electronics, for devices such as optoelectronic modulators, transistors, on-chip biosensors and tunneling barriers. The innovation was first published online in prestigious scientific journal Nature on 11 December 2013.
