Extraordinarily Bound Quasi-One-Dimensional Trions in Two-Dimensional Phosphorene Atomic Semiconductors
We report a trion (charged exciton) binding energy of ∼162 meV in few-layer phosphorene at room temperature, which is nearly 1–2 orders of magnitude larger than those in two-dimensional (2D) transition metal dichalcogenide semiconductors (20–30 meV) and quasi-2D quantum wells (∼1–5 meV). Such a large binding energy has only been observed in truly one-dimensional (1D) materials such as carbon nanotubes, whose optoelectronic applications have been severely hindered by their intrinsically small...[Show more]
