New polaritons multi-valley model may help valleytronics research

Researchers from the Institute for Basic Science (IBS) in Korea published a new paper that models the behavior of polaritons in microcavities, nanostructures made of a semiconductor material sandwiched between special mirrors (Bragg mirrors).

The new research helps to understand polaritons, microcavities and have potential implications for future valleytronics devices - such taht use valleys of polaritons. The IBS researchers have generated a theoretical model for valley polarization.
