It must be understood that superconductivity is not merely an extrapolation of most conductors' tendency to gradually lose resistance with decreasing temperature; rather, it is a sudden, quantum leap in resistivity from finite to nothing. A superconducting material has absolutely zero electrical resistance, not just some small amount Superconductivity was first discovered by H. Kamerlingh Onnes at the University of Leiden, Netherlands in 1911. Just three years earlier, in 1908, Onnes had developed a method of liquefying helium gas, which provided a medium with which to supercool experimental objects to just a few degrees above absolute zero. Deciding to investigate changes in electrical resistance of mercury when cooled to this low of a temperature, he discovered that its resistance dropped to nothing just below the boiling point of helium.

Yong-Jihn Kim Theme Song (Composer: Michael Bonet) 2006 IOP Reception(IPod Nano winner!), Batimore, MD Hello! I have been working on superconductivity more than 15 years! During the time, I found some serious fundamental problems in our understanding of superconductivity and tried to resolve those problems. This website summarizes the current status of this effort. I wish it could be helpful for many people. Yong-Jihn Kim, Associate Professor of Physics UPR-Mayaguez Recent work 1: Revised Theory of the Josephson Effects: Just published in Journal of Applied Physics, Vol. 103, 103902, (2008) Highlighted in Virtual Journal of Applications of Superconductivity, Vol. 14, issue 11, June 1, 2008 In 1962 B. Josephson predicted the Josephson effects. He won the Nobel Prize in Physics in 1973 for the contribution. Nevertheless, there are still some unsolved fundamental problems, such as the sign problem in the AC Josephson effect, the threshold behavior in the DC Josephson effect, and etc. This paper introduces a Cooper pair wavefunction approach to the Josephson effects. This method is more powerful and error-free, compared to the previous techniques. We have found that SIS junctions have a material-dependent threshold resistance, shown in the figure below,which explains why MgB2 SIS junctions don't show the supercurrent for the big gap! In addition we have found a more accurate formula for the temperature dependence of the supercurrent.

Superconductivity Superconductivity is a phenomenon which occurs in certain materials and is characterized by the absence of electrical resistivity. Until recently, this phenomenon had been restricted to metals and alloys with transition temperatures of less than 23K. In 1986, superconductivity was discovered in a ceramic material. This precipitated an onrush of ceramic based superconductors with transition temperatures as high as 120K. The ceramic-based materials are commonly known as high temperature (HTc) superconductors while the metallic and alloy materials are called low temperature (LTc) superconductors. Currently, only low temperature superconductors are of interest to the magnet designer and manufacturer. Superconductors are divided into two types depending on their characteristic behavior in the presence of a magnetic field. Type I superconductors are comprised of pure metals, whereas Type II superconductors are comprised primarily of alloys or intermetallic compounds. Both, however, have one common feature: below a critical temperature , T c , their resistance vanishes.

Skip navigation Entire Site OE only U.S. Department of Energy OE Home About Us Our Organization ... Site Map Quick Reference You are here: DOE Home OE Home Our Work HTS High Temperature Superconductivity (HTS) Superconductivity is a phenomenon observed in certain metals and ceramic materials that, when cooled to very low temperatures, have no electrical resistance. It has the potential for bringing a more fundamental change to electric power technologies than has occurred since electricity use became widespread nearly a century ago. The fiber optic "information superhighway" was constructed by replacing copper wires with a higher-capacity alternative. Superconductivity provides a comparable "energy superhighway" by replacing copper wires with a ceramic superconducting alternative that has higher capacity while eliminating resistive losses. High-temperature superconductivity (HTS) power equipment has the potential to become a key twenty-first century technology for improving the capacity, efficiency, and reliability of the electric system. For example, higher capacity HTS power lines could provide transmission and distribution systems with smaller footprints that allow additional capacity to be placed in service along existing rights-of-way. Fault current limiters (FCLs) are another emerging technology. FCLs have the potential to save utilities money and make the modern grid more efficient by protecting electric grid equipment from damages and by helping to avoid outages

Superconductivity Superconductivity is a phenomenon occurring in certain materials at low temperatures , characterised by the complete absence of electrical resistance and the damping of the interior magnetic field (the Meissner effect In conventional superconductors , superconductivity is caused by a force of attraction between certain conduction electrons arising from the exchange of phonons , which causes the conduction electrons to exhibit a superfluid phase composed of correlated pairs of electrons. There also exists a class of materials, known as unconventional superconductors , that exhibit superconductivity but whose physical properties contradict the theory of conventional superconductors. In particular, the so-called high-temperature superconductors superconduct at temperatures much higher than should be possible according to the conventional theory (though still far below room temperature .) There is currently no complete theory of high-temperature superconductivity. Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminium , various metallic alloys , some heavily-doped semiconductors , and certain ceramic compounds containing planes of copper and oxygen atoms . The latter class of compounds, known as the
