#Nanotechnology is revolutionising the way we live by making #microelectronic systems even smaller, enabling new developments in diagnosis and treatment in medicine, and giving the surfaces of materials new self-cleaning properties – to name just a few examples. #Nanostructures’ unique properties are partly due to the fact that the dimensionality of the materials is limited – such as by only allowing a crystal to grow in two directions or even just one direction instead of three. In essence, ‘one dimensional’ means arranging atoms in a chain. ‘However, an atom chain cannot exist in empty space but must be placed on a substrate,’ explains Prof. Dr. Alexander Schneider from FAU’s Chair of Solid-State Physics. ‘Doing this can cause the desired properties – magnetism in our case – to disappear again. Developing an understanding of these low-dimensional systems is a key research priority, as they are increasingly dominating the properties of magnetic data storage.’
