What's next in spintronics? Well, the p\phantom\rule00exs\phantom\rule00exe\phantom\rule00exu\phantom\rule00exd\phantom\rule00exo\phantom\rule00exs\phantom\rule00exp\phantom\rule00exi\phantom\rule00exn is a discrete electronic degree of freedom that is tunable by an electric field, and suitable for application. The authors show that zigzag phosphorene nanoribbons support two incarnations of pseudospin: edge (where electron transport can be restricted to only one of the ribbon edges) and layer (transport through only one layer in a bilayer nanoribbon). The researchers describe a field-effect transistor that generates pseudospin-polarized current, and a pseudospin valve that selectively transmits only one pseudospin polarization. In particular, the edge-pseudospin valve is predicted to be remarkably robust.
