Abstract
The temperature-dependent behavior of the solid composition
xs of AlxGa1-xAs has systematically
been studied as a function of gas phase composition xg in an
optimized horizontal metalorganic vapor phase epitaxy reactor at
atmospheric pressure. Up to a temperature of 660 °C the Al
incorporation is constant but slightly exceeds the Ga incorporation.
Above this temperature the Al incorporation strongly increases with
temperature. This behavior is most probably related to a change in
growth mechanism from mass transport limited growth to a regime where
the growth is controlled by thermodynamics, especially for the gallium
species.
