Black 5nm Graphene Thermal Conductive Material
Graphene is practically a one atom thick layer of carbon atoms, densely packed in a hexagonal (honey comb) lattice. The carbon-carbon bond length in graphene is about 0.142 nanometers. It is already known that it has unbelievable strength and conductivity, both of which are a result of its structure.
Graphene differs from conventional 3D materials in that it is a semi-metal or zero-gap semiconductor. It has a remarkable electron mobility at room temperature and it has been showed that electrical current going through it can magnetize it.
