Abstract
An electrical interconnection. In order to efficiently conduct electrical current in small-scale structures and at high frequencies, the electrical interconnection has a channel portion which includes at least one channel layer made of a weak topological insulator material and having a top surface with a plurality of grooves extending from a first terminal to a second terminal of the electrical interconnection, wherein the top surface and a bottom surface of each groove are insulating, whereas each side surface of each groove includes a conducting zone with a pair of topologically protected one-dimensional electron channels.
