Electrical transport and ESR studies were performed on the state-of-theart GaN layers grown on sapphire substrate using metal organic chemical vapour deposition technique. For undoped samples electron concentration below 2×10^{17} cm^{-1} and mobility up to 500 cm^{2}/(V s) were achieved whereas hole concentration up to 7×10^{17} cm^{-3} and mobility about 16 cm^{2}/(V s) were obtained for intentionally Mg doped samples and subsequently annealed. Temperature dependence of mobility was discussed. ESR revealed the presence of two resonance absorption lines. One of them with g_{⊥}=1.9487 and g_{∥}=1.9515, commonly observed in n-type GaN was due to shallow donor. The second ESR line was an isotropic one of g=2.0032 and it is discussed.
