Data for: Trions and biexcitons in ZnO/ZnMgO, CdSe/ZnS and CdSe/CdS core/shell nanowires
In our paper we present a theoretical study of the trion and biexciton in a nanowire in the framework of the effective-mass model. Our calculations for the ZnO/ZnMgO, CdSe/ZnS and CdSe/CdS core/shell cylindrical shaped nanowires show that the trion and biexciton binding energy in nanowires are size-dependent and for the same input parameters the biexciton binding energy is always larger than the binding energy of the trion. We demonstrate that the trion and biexciton remain stable in CdSe/ZnS nanowire with the increase of the dielectric shell, while in ZnO/ZnMgO nanowire they become unstable when the surrounding dielectric shell exceeds 2.5 nm and 2 nm, respectively. We suggest the mechanism of formation of the trion via associative ionization of the biexciton.
