Using a newly discovered phase of graphene, Purdue researchers have developed a "topological circulator" that may improve how information is routed and processed on a chip.

In a recent breakthrough by Purdue University, researchers have devised a method utilizing the remarkable properties of graphene to support unidirectional electromagnetic waves on its edge, more simply, a new form of potentially lightspeed communications.

The topological circulators developed by Purdue scientists are the smallest one-way routers of signals in the world and could be a breakthrou...
