Modification in preparing of superconducting materials

Abstract


The development of superconductors is widely used in different kinds of area, especially in electricity transportation. Since there is no need to transform the electricity to voltages with large differences and a higher efficiency obtained in generating electricity, resulting huge savings with the use of national grid made of superconductors. Superconductivity appears in the way that certain materials can conduct electric current with zero resistance at low temperature. Different materials, mainly metals and alloys are used to be treated as superconductors in this project. The graphene layers are first prepared with the chemical vapour deposition and the target materials will be made in the form the metal-intercalated tri-layer or bilayer graphene. Superconducting quantum interference device (SQUID) will finally be used under the temperature at related existing critical temperature to study the relationship between the structures of prepared materials and the electric current flow in SQUID.
