Iranian researchers present new model to strengthen superconductivity at higher temperatures

Iranian scientists from Institute for Advanced Studies in Basic Sciences in Zanjan presented a new model that expresses the possibility for the formation of superconductivity properties at high temperature, independent from the type of the material. The idea can be used in the production of various electronic nano-pieces in electronics and communications industries. One of the reasons that superconductivity characteristic is not used in today technologies is that the characteristic is degraded as the temperature increases. On the other hand, it is very expensive to provide cold conditions for the good performance of superconductive materials. Efforts are currently being made to produce superconductors that are active at appropriate temperatures. The majority of the researchers try to produce high-temperature superconductors by combining various materials. This research presents a model that enables the formation of superconductivity at high temperatures, independent from the material type. Result of the research show that there is a possibility of the creation of intra-layer superconductivity in graphene nanostructures. In this type of superconductivity, charge carriers that are condensed and play a major role in the creation of superconductivity belong to different layers of bi-layer graphene. There is unique symmetry in this type of superconductivity that results in the better reduction of the phenomenon at temperatures higher than 0 K. It was always believed that superconductivity would become weak and was destroyed at temperatures higher than 0 K. According to the results, very accurate magnetic sensors can be designed, which are able to measure very weak magnetic waves of brain and to diagnose the disease by investigating the mechanism of the brain. Results of the research have been published in Physical Review Letters, vol. 108, issue 14, April 2012, pp. 147001-147005.
