This material, isolated only in 2004, was approached by a team from Rice University as a solution to the dissipation of heat generated by our dear chips.

Graphene has indeed an excellent thermal conductivity: 5000 Watts per meter per Kelvin. By comparison, the diamond, which previously held the record less than 2600 Wm -1. K -1 and a metal such as copper ceiling was 390 Wm -1. K -1. Even when the graphene is deposited as a film on a substrate of silica, its thermal conductivity is maintained at 600 Wm -1. K -1. Under the same conditions, copper does more than 250 Wm -1. K -1. Graphene could thus accelerate the dissipation of heat from both the transistors within the components and also components of the surface outside. With this, the chip could be clocked at higher frequencies, or be made more complex 3D example.
