Single-layer graphene – Properties and Applications |
What is Single-layer Graphene? Single-layer graphene consists of a single layer made of carbon atoms. The sp2 covalent link between each carbon atom makes single-layer graphene the stiffest and thinnest material in the universe (its fracture strength is around 200 times that steel). It is nearly transparent and absorbs 2.3% light. It has a thermal conductivity as high as 5300 W/m. K is greater than diamond and carbon nanotubes; its resistivity is only 0.96x10-6 O.cm, which is lower than silve
