Unambiguous symmetry assignment for the top valence band of ZnO by magneto-optical studies of the free A-exciton state
Lu Ding, Chunlei Yang, Hongtao He +5
We studied the circular polarization and angular dependences of the magneto-photoluminescence spectra of the free A-exciton 1S state in wurtzite ZnO at T = 5 K. The circular polari…
