Perfect quantum portal emerges at exotic interface

Nanowerk  June 26, 2019
A team of researchers in the US (University of Maryland, UC Irvine) has observed perfect Andreev reflection in point-contact spectroscopy—a clear signature of Klein tunneling and a manifestation of the underlying ‘relativistic’ physics of a proximity-induced superconducting state in a topological Kondo insulator. The findings shed light on a previously overlooked aspect of topological superconductivity and can serve as the basis for a unique family of spintronic and superconducting devices, the interface transport phenomena of which are completely governed by their helical topological states…read more.
