A team of scientists have published a study on the material called graphene that might be the key to the next wave of electronic devices. Because graphene can carry electrons without any resistance at room temperature, which in physics is called ballistic transport, it is an efficient conductor of electricity.

Because graphene can carry electrons without any resistance at room temperature, which in physics is called ballistic transport, it is an efficient conductor of electricity.
Conductors currently used in electronic devices, like copper, are resistant to the electrons and are slower at transferring the electricity than graphene has proven to be.
Scientists from Georgia Tech grew small graphene ribbons on the side of silicon carbide ridges, instead of making a sheet of graphene and cutting out individual ribbons.
They heated the material to one thousand degrees Celsius, which evaporated the silicon, and left a 40 nanometer wide ribbon of graphene.
The results of the study found it to be ten times more effective than previous theories of electron transport.
Other experts say that when applied to a larger scale, the minor imperfections on a graphene ribbon would slow down the flow of electrons.
