U.S. scientists have developed ultra-thin superconducting field-effect transistors

U.S. scientists using self-designed, precise arrangement of atoms layer by layer technique, constructed of a thin superconducting field-effect transistors, to insight into the insulating material into the environment, the details of high-temperature superconductors. Post published on the same day the "Nature" magazine of the breakthrough will enable scientists to better understand high-temperature superconductivity, to accelerate the development of electronic equipment without resistance process. Cuprates common insulation material circumstances in which state transition from insulating to superconducting state? This transition AD8362ARUZ occurs, what happens? These problems have been plaguing physicists. One way to explore this transition is applied electric field to increase or decrease the concentration of free electrons in the material, and to observe its effect on the load current capacity of the material. But to the cuprates superconductors do this, you need to build thin film composition consistent and up to 10 billion V / m electric field. If the U.S. Department of Energy physicist Yiwan Bo Popovich led the Brookhaven thin film research team previously used the molecular beam epitaxy to create such a superconducting film, the technology BTS711L1 in the manufacture of an atomic layer at a precise control of each can thickness. They recently demonstrated, using molecular beam epitaxy to produce thin-film, the single ketone salts can exhibit high temperature superconductivity does not decay, they use this method to produce ultra-thin superconducting field-effect transistors. As the basis of all modern electronic devices within a standard field-effect transistor, a semiconductor material at one end of the current from the device, "the source electrode to the other end of the delivery of the" power pole; a thin insulator as a third electrode is "responsible for the control FET gate electrode transistors when the insulator is applied to a particular ADS7846E gate voltage, the gate electrode will be turned on or off, but there is no known insulators can antagonize the induction of the ketone salts required for high-temperature superconductivity within the high electric field, therefore, the standard field-effect transistor design is not suitable for high temperature superconducting field-effect transistors. Bozovic team can use a liquid conductive electrolyte to separate charge. When the external voltage is applied toward the electrolyte, the electrolyte in the positively charged ions move toward the negative electrode, negatively charged ions move toward the positive electrode, but when the reach the electrode, the ions will suddenly stop moving, like hit the "brick wall as the electrode "wall load of the electric field between oppositely charged equal to more than 100 million volts / meter. The newly developed superconducting field-effect transistors, high-temperature superconductors compound model (La - Sr - Cu - O) up to the critical temperature of 30 Kelvin degrees, 80% of its maximum value is 10 times the previous record. Scientists can use the transistor to the high-temperature superconductivity research and basic principles of physics. Superconducting field-effect transistor wide range of applications. MAX1748EUE Semiconductor field-effect transistors based on energy consumption, while the superconductor without resistance and no energy. In addition, the arrangement of atoms to create a thin layer structure enable scientists to make better use of external electric field to control the superconductivity. Bozovic said that this is just the beginning, high-temperature superconductors, there are many secrets yet to be exploring, with its mysterious "veil lifted one by one, in the future to produce energy-efficient ultra-fast high-temperature superconductors.
