Researchers move an atom inside a crystal and investigate its function
Nanotechnology is a thriving science. Parts for computers for example are becoming smaller and more precise by the minute. One of the most efficient computers would be the so-called quantum computer. Up to now, its existence has been merely a concept that is based on the laws of quantum mechanics. Here, the ability to control the state of single atoms is decisive. For the first time ever, scientists of Kiel University have managed to move single atoms vertically inside a crystal. This is important for the further development of nano structures. Simultaneously, the physicists found a method for measuring a transistor-like behaviour of single atoms. These findings have recently been published in the scientific magazine Nature Communications (January, 3rd, 2014) as well as in the renowned Physical Review Letters.
