ELECTRICAL INTERCONNECTION COMPRISING A TOPOLOGICAL INSULATOR MATERIAL

摘要

The invention relates to an electrical interconnection (1). In order to provide means for efficiently conducting electrical current in small-scale structures and at high frequencies, the invention provides that the electrical interconnection has a channel portion (50) which comprises at least one channel layer (10) made of a weak topological insulator material and having a top surface (11) with a plurality of grooves (12) extending from a first terminal (2) to a second terminal (4) of the electrical interconnection (1), wherein the top surface (11) and a bottom surface (12.2) of each groove (12) are insulating, whereas each side surface (12.1) of each groove (12) comprises a conducting zone (14) with a pair of topologically protected one-dimensional electron channels (15).electrical interconnection comprising a topological insulator material
