>Researchers at DLR have for the first time diffracted a beam of helium atoms through an ultrathin graphene membrane. The atomic matter waves created a characteristic wave pattern behind the membrane.
>DLR researchers have succeeded, for the first time, in diffracting matter waves of atoms through a solid; until now, this had only been possible with electrons and neutrons. This opens up new avenues in materials research – enabling both the investigation of samples sensitive to radiation and the development of radiation-resistant materials.
