Cutting the graphene cake
04 Sep 2012
Researchers at The University of Manchester have demonstrated that graphene can be used as a building block to create new 3D crystal structures which are not confined by what nature can produce.
The Manchester researchers have created atomic crystals using graphene
Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research.
Writing in Nature Materials, the scientists show that a new side-view imaging technique can be used to visualize the individual atomic layers of graphene within the devices they have built. They found that the structures were almost perfect even when more than 10 different layers were used to build the stack.
This surprising result indicates that the latest techniques of isolating graphene could be a huge leap forward for engineering at the atomic level.
This development gives more weight to graphene's suitability as a major component in the next generation of computer chips.
