Interplay of the Trion Singlet and Triplet State Transitions in Magnetooptical and Time-Resolved Investigation of ZnSe/Zn(S,Se) Single Quantum Wells
Abstract
Negatively charged trions are investigated for ZnSe single quantum wells embedded in ternary barriers. Polarization and excitation dependent photoluminescence measurements were performed in magnetic fields up to 11.8 T. From these measurements we are able to develop an energy-term scheme for the spin-singlet and the spin-triplet state of the trion.
