Abstract : This program successfully demonstrated growth of ordered Al(1-x)In(x)P, lattice-matched to GaAs, by metalorganic chemical vapor deposition (MOCVD). Films were characterized by transmission electron diffraction, double-crystal X-ray rocking curve analysis, and low-temperature photoluminescence. Weak birefringence was seen by spectroscopic ellipsometry. Strong ordering in Al(1-x)In(x)P is best achieved at a growth temperature of approx. 675 deg C. jg
