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.
