Temperature-dependent Hall-effects in MOCVD-grown Si-doped GaN epilayers were measured as a function of temperature in the range 10-800 K. The results were satisfactorily analyzed in terms of a two-band model including the F and impurity bands at lower temperatures than room. The F band electrons are dominant only high temperatures. The ionized impurity scattering is the most important in the F band except at very high temperatures.
