The diffusion characteristics of Mg dopant in MOVPE-grown GaN was studied. Cp2Mg, TMGa and NH3 were used as precursors. The Al2O3 was applied as a substrate. The temperatures range from 1000 C to 1300 C ensured conditions for device quality layers growth. Applying these temperatures, the back diffusion of magnesium were observed. Similar phenomenon was measured in Zn doped GaAs and InP.
