Abstract
An electrical device includes a current transport layer formed using a layer of a topological material selected from the group of a topological insulator, a quantum anomalous hall (QAH) insulator, a topological insulator variant, and a topological magnetic insulator. In one embodiment, the current transport layer forms a conductive wire on an integrated circuit where the conductive wire includes two spatially separated edge channels, each edge channel carrying charge carriers propagating in one direction only. In other embodiments, an optical device includes an optical layer formed using a layer of the topological material. The optical layer can be a light absorbing layer, a light emitting layer, a light transport layer, or a light modulation layer.
