Graphene gets a bandgap for opto-electronics

While graphene has some amazing physical, optical and mechanical properties, its lack of a natural bandgap limits its use in electronics. Methods of varying complexity have been found to add bandgaps, and now there is another tool in the box – a chemical whose molecules self-assemble into an evenly-spaced flat lattice as they bond down ...
