How can you perforate an atomic layer of material and leave the one underneath intact? Scientists at TU Wien (Vienna) developed a technique for processing surfaces on an atomic scale. Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact. However, on the level of individual atomic layers, such a feat has now been achieved - a nano-structuring method has been developed at TU Wien (Vienna), with which certain layers of material can be perforated extremely precisely and others left completely untouched, even though the projectile penetrates all layers.
