American scientists develop ultra-thin superconducting field-effect transistors 2

As the foundation of all modern electronic devices, the standard field-effect transistor uses a semiconductor material to transport current from the "source" electrode at one end of the device to the "drain" electrode at the other end; A thin insulator serves as the third electrode "gate" electrode responsible for controlling the field-effect transistor. When a specific gate voltage is applied to the insulator, the gate electrode will open or close. However, there is no known insulator that can counteract the high electric field required to induce high-temperature superconductivity inside the ketone acid salt. Therefore, the design of standard field-effect transistors is not suitable for high-temperature superconducting field-effect transistors.

The Borovich team used a conductive liquid electrolyte to separate charges. When an external voltage is applied to the electrolyte, positively charged ions in the electrolyte move towards the negative electrode, and negatively charged ions move towards the positive electrode. However, when they reach the electrode, the ions suddenly stop moving, like hitting a "southern wall". The electric field energy between equal amounts of opposite charges loaded on the electrode "wall" exceeds 10 billion volts per meter. transistors
