Graphene coating enables CNT growth on normally unsuitable substrates

Researchers from Rice University and the Honda Research Institute USA found that using graphene coating may enable carbon nanotube (CNT) growth on substrates which are normally unsuitable for this task.

A diamond for example conducts heat very well (five times better than copper) but it has a very low available surface area. Coating diamonds with graphene enables the growth of vertically aligned CNTs on the diamond - which creates a very efficient heat sink.

The researchers say that this method may have other applications in advanced electronics.
