SnS is found to be a promising valleytronics material

Researchers from Berkeley Lab discovered that Tin(II)-Sulfide (SnS) is a promising valleytronics material as its valleys have different shapes and responses to different polarizations of light. This property means that in SnS it is easy to read valleytronics data bits.

The researchers have shown that SnS is able to absorb different polarizations of light and then selectively re-emit light of different colors at different polarizations. In such a material, it is possible to concurrently access both the usual electronic and valleytronic degrees of freedom.
