Schematic representation of the electronic behavior in the device described in the article. The arrows represent quantum channels where electrons propagate. Eectrons are allowed to change direction only at the central area, resulting under certain conditions in constructive interference. Credit: CIC nanoGUNE In a recent article published in Physical Review Letters a research collaborative has reported new insights into the electronic conduction and interference on 2-D topological insulators—an e..
