| 英文摘要 | Electron mobility limited by nitrogen vacancy scattering was taken into account to evaluate the quality of n-type gan grown by metal-organic vapor phase epitaxy. the nitrogen vacancy scattering potential used for our mobility calculation has to satisfy two requirements: such potential is (1) spatially short range, and (2) finite and not divergent at the vacancy core. a square-well potential was adopted to calculate the mobility, because it satisfies not only these two requirements, but also simplifies the calculation. as a result, the estimated mobility shows a t-1/2 temperature dependence, and is very sensitive to the potential well width. after introducing the nitrogen vacancy scattering, we obtained the best fitting between the calculated and experimental results for our high quality sample, and it was found that the measured mobility is dominated by ion impurity and dislocation scatterings at the low temperatures, but dominated by optical phonon and nitrogen vacancy scatterings at the high temperatures.
