Examples of them6 bound to isoelectronic dopants can be used to efficiently extract (*) light from indirect semiconductors.
When these particles are bound to a neutral donor and undergo photoluminescence spectroscopy, a two-electron satellite feature is observed in the spectrum. These particles are the subject of much 3 study in CuCl quantum dots, including a "bi" version of these particles that's typically abbreviated XX. These particles create a system of energy levels below the conduction band whose mathematical expression includes a term exactly as that of the hydrogen atom's energy levels. Examples of them6 bound to isoelectronic dopants can be used to efficiently extract (*) light from indirect semiconductors. These particles can exist as tightly-bound or weakly-bound, in the latter case existing across many unit cells; those two types are respectively named for Frenkel, and Mott and Wannier. They can efficiently couple to9 photons to form a namesake polariton quasi-particle because these quasi-particles are electric dipoles. For 10 points, name these electron-hole pairs bound by a Coulomb attractive force.
