Engineering edge-state currents at the interface between narrow ribbons of two-dimensional topological insulators
We consider a junction between two semi-infinite narrow ribbons of a two-dimensional (2D) topological insulator (TI) and calculate the electron current through the interface carried by one-dimensional (1D) edge states formed in the bulk band gap. In addition to an abrupt interface between ribbons, w...
