Imagine a tablet device as thin as a piece of paper, folded conveniently in your pocket. Or a 3D TV that wraps around the walls of an entire room in your home. With applications that are nothing short of science fiction, it is no wonder that graphene-based research continues to fascinate scientists.

Graphene is a single-layer sheet of carbon atoms arranged in a honeycomb lattice that is incredibly strong (about 100 times stronger than steel), low weight, and conducts heat and electricity with great efficiency. Graphene was first made in 2004 by Andre Geim and Kostya Novoselov at the University of Manchester – a discovery that earned the two physicists a Nobel Prize in 2010. Using a number of experimental facilities at the Canadian Light Source, a group of scientists successfully measured the smallest optical density of single layer graphene so far, giving further insight into the design and fabrication of graphene-based nanodevices, which can potentially enable the future electronic gadgets.

This photo shows the research team that undertook this study: CLS scientists (l-r) Dr. Jian Wang, Garth Wells, Dr. Ferenc Borondics, postdoctoral fellow Dr. Swathi Iyer and University of Saskatchewan physicist Dr. Michael Bradley conduct researcher on a number of CLS beamlines including Mid-IR, SyLMAND and SM. Other research team members (not shown) are Dr. Scott Payne, Electron Microscopy Center and Dr. Srinivasan Guruvenket, Centre for Nanoscale Science and Engineering.
