Scientists from Tokyo Metropolitan University have discovered that charged states made of two electrons and a positively charged hole (or vice versa) on atomically thin rolls of carbon atoms have a structure-derived "handedness" in how they interact with light. While electron-hole pairs, or "excitons," were known to keep the chirality of the underlying nanotube, the team showed that adding a charge to create "trions" does not change this property.
