The researchers said that the researchers chose the chemical nature is very stable, almost no impurities containing potassium tantalate as an insulating material, and then the solid insulation material placed in an ionic liquid, the surface of the insulating material will spontaneously form an electric double layer. In this electric field effect, the electrical insulating board has a superconductivity, in the absolute temperature of 0.05 open (minus 273.1 degrees Celsius) environment to achieve a zero resistance.
It is reported that the research and development of superconducting materials to the main use of two major methods, one is mixed with several kinds of metal metallurgical methods, and the other is the insulator as the main material mixed with impure chemical method, the most representative of the copper Oxide high temperature superconducting material.
The use of electric field effect of the method can be described as the development of superconducting materials, a new means, it can make potassium tantalate such as the original people that can not become mica insulation sheetsl has a superconductivity for the future development of higher critical temperature of the new Superconducting materials laid the foundation.
