Rezumat

Continuous GaN films were grown on the top of cracked Si-doped n+-GaN epilayers by MOCVD techniques. Raman-scattering studies of the samples indicated strain-free top GaN film. The biaxial compressive stress estimated by using X-ray diffraction analysis was as low as 0.036 GPa for sample grown under optimized conditions. The results obtained show that the use of an intermediate relaxed n+-GaN:Si layer is perspective for growing high quality GaN films.
