Researchers explored dipole interseries transitions between yellow and green exciton series in cuprous oxide, including the complex valence-band structure, by extending previous studies on the spectrum of complex green exciton resonances. The calculations on interseries transitions were enhanced by a more comprehensive treatment of the valence-band structure, in addition to optical transitions between different exciton states and transitions from the crystal ground state.
We study dipole interseries transitions between the yellow and green exciton series in cuprous oxide including the complex valence-band structure. To this end, we extend previous studies of the spectrum of complex green exciton resonances [P. Rommel, P. Zielinski, and J. Main, Phys. Rev. B 101, 075208 (2020)] to optical transitions between different exciton states in addition to transitions from the crystal ground state. This allows us to augment the calculations on interseries transitions using a hydrogenlike model [S. O. Kruger and S. Scheel, Phys. Rev, B 100, 085201 (2019)] by a more comprehensive treatment of the valence-band structure.
