      A quasi-thermodynamic analysis of the MOVPE growth of AlxGa1-xN alloy using TMGa, TMA1 and ammonia has been proposed. The effect of varying growth conditions (growth temperature, reactor pressure, input V/III ratio, hydrogen pressure fraction in the carrier gas and the decomposed fraction of ammonia) on the distribution coefficient of Al has been calculated. In the case of AlxGa1-xN, preferential incorporation of Al is predicted. The calculated relationship between input vapour and deposited solid composition has been compared with data in the literature. A good agreement between the calculated and the experimental composition shows that our improved model is suitable for applying to the AlxGa1-xN alloy grown by MOVPE. (C) 2000 Elsevier Science B.V.
