Abstract: The contour of the energy bandgap of III-V quinary, AlGaInPAs, lattice matched to GaAs has been calculated, and the segregation coefficient of Al in the solution used for growing AlGaInPAs/GaAs has been analysised. The effect of supercool on the solid composition of AlGaInPAs on GaAs, resulted from Al's segregating from the solution, has been demonstrated experimentally, no effect on other characteres was found.
