26 DESIGN007 MAGAZINE I AUGUST 2018 Empa researchers and colleagues from the Max Planck Institute for Polymer Research in Mainz and other partners, have achieved a breakthrough to be used for precise nanotransistors or possibly even quantum computers, as the team reports in the current issue of the scientific journal Nature. A material that consists of atoms of a single element but has completely different properties depending on the atomic arrangement. The graphene ribbons, which are only a few carbon atoms wide and exactly one atom thick, have very different electronic properties depending on their shape and width: conductor, semiconductor or insulator. Source: Empa Quantum Chains in Graphene Nanoribbons All 3D package models in this article were auto-generated by the free Library Expert Pro using package dimensions provided by the component manufacturer datasheet. Part 2 of this feature will be published in the September issue of Design007 Magazine, and the collection will made available online in its entirety.
