Material can be created from graphene — research
When two sheets of graphene are connected at a certain angle, the resulting material becomes either a very efficient conductor or an excellent insulator.
Graphene has already established itself as an amazing and versatile material. In a new study, scientists discovered new properties in it that could lead to a breakthrough in the field of high-temperature superconductors and quantum computing.
Spun with the so-called "magic angle" graphene acquires new properties. By combining two sheets of graphene one atom thick at different angles, the researchers obtained a material with alternating sections of superconductivity.
“These devices will help develop new-generation high-temperature superconductors, topological devices for quantum information processing, and low-energy technologies,” says physicist Yuan Cao of MIT.
Scientists have conducted a series of experiments with the angle of application of graphene sheets. As a result, they found that a “magic angle” of 1.1 degrees endows graphene with new properties of insulation or superconductivity.
The angle creates a gradient that induces current, and the wider it is, the more modest physical transformations. Researchers identified all the characteristics observed with a change in angle, describing the changes in their work. In the future, the experimental results will allow the creation of improved structures from twisted graphene.
Research in this area is just beginning, and a sheet of several layers of graphene superimposed at a certain angle can find application in physics and materials science.
