摘要：
Growth rate as a function of growth temperature has been studied for MOVPE InN. In the temperature range of 500-600 degreesC, growth rate is increased with increasing growth temperature while TMI supply is constant, and shows a saturation against the increase in TMI supply. At 650 degreesC, on the other hand, such a saturation is not seen for TMI supply up to 28 mu mol/min. As a result of this, a growth rate as high as 0.8 mum/h is obtained at 650(.)degreesC Activation energy (similar to0.76 eV) for saturated growth rate is in good agreement with that (0.79 eV) reported for the thermal decomposition of NH, showing that the growth-rate is dominated by the active nitrogen supply and its saturation is due to the deficiency of active nitrogen. At around 650 degreesC, growth rate is lower than that expected from the values at lower temperatures. This seems to be due to the decomposition of grown InN.
