Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

As computer chips continue to get smaller and more complex, the ultrathin metallic wires that carry electrical signals within these chips have become a weak link. Standard metal wires get worse at ...

Current copper wiring in computer chips struggles to carry electricity efficiently as circuits shrink to the nanoscale, leading to a process that generates heat and limits performance. These materials ...
