1. An electrical device, comprising:

  • a current transport layer formed using a layer of a topological material, the topological material being selected from the group of a topological insulator, a quantum anomalous hall (QAH) insulator, a topological insulator variant, and a topological magnetic insulator, wherein the topological insulator and the QAH insulator both have an insulating energy band gap in the bulk and conducting edge or surface states, the topological insulator variant is formed from a topological insulator material, and the topological magnetic insulator comprises an antiferromagnetic insulator; and

    at least one electrode in electrical contact with the current transport layer.
