Single-atom Transistor Can Make IT Applications More Energy Efficient


Published Date : Aug 20, 2018

Researchers from the Karlsruhe Institute of Technology (KIT) have developed the world’s smallest transistor so far that works through the controlled reversible movement-called repositioning-of a single atom. The transistor has also demonstrated successful use in the solid state with the use of a gel electrolyte, improving its handling and safety parameters by a significant measure.

Researchers mention that this single-atom, miniature transistor consumes very less energy, which could open up new horizons for the IT industry. Transistors are central to a variety of digital data processing systems in smartphones, computing centers, personal computers or embedded systems for a wide range of applications from televisions to airplanes. As the rate of digitization across the globe rises, the amount of energy required to run electronic products is also rising exponentially. In this scenario, the use of this new transistor, which has proved to work on energies much lesser required for conventional silicon technologies, can enhance the energy efficiency of a variety of applications in the IT sector.

The transistor has also demonstrated proper functionality at temperatures as low as near absolute zero as well as room temperature. This could also prove to be of immense importance for a number of applications in the IT sector. The new transistor does not use any semiconductors and consists only of metal. This leads to extremely low electric voltage and consecutively very low consumption of energy. The electrolyte used for the transistor is made by gelling a liquid silver electrolyte with pyrogenic silicon dioxide, providing the electrolyte the handling-related advantages of solid with several benefici
