The Γ[sub 5] and Γ[sub 6] free excitons have been identified in GaN from emission measurements. Another emission peak is also observed which we believe to be the longitudinal free exciton. These measurements along with electrical measurements, which show the sample to have very high peak mobility, attest to the high quality of the sample. © 2000 American Institute of Physics.
