From the new properties of graphene, a group of researchers from MIT grants U.S. Department of Energy was able to create the conditions for identifying such characteristics of monomeric carbon plates, which may potentially lead to the creation of the mythical quantum computers . Now experiment with the creation of graphene raised operating temperatures near absolute zero (0.3 degrees Celsius) and with a magnetic field strength of 35 tesla, which is 10 times greater than the strength of the magnetic field in a typical medical EMRT-scanner.
Now the new properties of graphene. At room temperature, the graphene wafer according to the current flowing both in the normal conductor, in one direction depending on the polarity. Under the influence of a powerful magnetic field (and low temperatures), the motion of electrons in graphene is subject to certain and that is important, repeatable patterns. The motion of electrons gained a recurring character and only at the edge of the graphene sheet. In this moving only those electrons whose spin direction are the same. Electrons with opposite spin angular momentum simply blocked. In other words, graphene acted as a filter for electrons. Placing graphene two powerful electromagnetic field, the researchers found two on the edge of the material flow of electrons, one moving clockwise and the other counterclockwise.
This experience has shown that graphene-based transistors can create analogues, which can be controlled condition (magnetic field), and the path of the transistor circuitry promises to be unlike the shorter. Related Products :
