Ions are an essential tool in chip manufacturing, but they can also be used to produce nano-sieves. A large number of electrons must be removed from the atoms for this purpose. Such ions either lose a large amount of energy or almost no energy at all as they pass through a membrane that measures one nanometer in thickness. Researchers report that this discovery is an important step towards developing novel types of electronic components made of graphene.
