The Nano-Sized Revolution

01 _ About

Today, microchips are not only found in computers and smartphones, but also in household appliances such as refrigerators and dishwashers. Switching elements on these microchips, the transistors, already consume more than 10% of the world’s electricity. If the Internet were a country, it would be the world’s sixth-largest energy consumer. The technology reduces the electrical voltage needed to perform logic operations on a microchip by a factor of 100, a 10,000-fold energy saving.


A team of researchers led by Prof. Dr. Thomas Schimmel, physicist and expert in physics and nanotechnology at the Institute of Applied Physics of the Karlsruhe Institute of Technology (KIT), developed what is probably the world’s smallest transistor. This works with a technical approach that does not use semiconductors for current control. This enables a very low electrical voltage and extremely low power consumption.


Unlike conventional quantum electronic devices, the transistor operates at room temperature and is made entirely of metal, reducing dependence on raw materials and semiconductors. The smallest transistor switches current by the controlled displacement of a single atom. With this quantum electronic element, switching energies are possible that are a factor of 10,000 lower than those of conventional silicon technologies.
