To have better insight into the energy transfer and defect creation processes occurring in the InGaN/GaN multiple quantum well (MQW) structures the detailed study of the Si-doped (18 ppm) GaN epitaxial layers in comparison with undoped GaN prepared by metal-organic vapor phase epitaxy (MOVPE) technology is proposed. It has been found that the Si doping plays significant role in the position and intensity level of the exciton and defect emission. Moreover, the Si doping resulted in passivation of defects.
