Electrical and optical devices incorporating topological materials including topological insulators

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