Free excitons with n=2 in bulk GaN

Free excitons with n=2 in bulk GaN

The direct observation of free A, B, and C excitons with n=2 in hexagonal bulk gallium nitride (GaN) by two-photon spectroscopy is reported. From these data, the band gaps, exciton binding energies, and hole masses for the three uppermost valence bands are calculated. © 1997 American Institute of Ph...
