    Abstract:
    The growth of InP/InAsxP1-x and InAlAs/InAsxP1-x heterostructures was studied using P and As sources. The As4 flux is incorporated much less efficiently into higher As percentage InAsP due to the higher strain in the grown InAsP film. The InP/InAsP multiple quantum wells showed photoluminescence at full width at half maximums of 12-19 meV at 4.2 K.
