Dynamics of resonantly excited excitons in GaN

Dynamics of resonantly excited excitons in GaN

Show other versions (1)

We present resonant fs pump-probe reflectance measurements of excitons in wurtzite GaN epilayers at different lattice temperatures. At 4 K we find that the exciton dynamics is dominated by trapping at defects via acoustic-phonon emission on a time scale of 16 ps. At temperatures above 60 K we observ...
