Abstract :
Compositional grading at hetero-interfaces in InP/Ga0.47In0.53As/InP structures was investigated utilizing X-ray CTR (crystal truncation rod) scattering method. InP/ Ga0.47In0.53As/InP structures were grown on InP(001) substrate by OMVPE (organometallic vapor phase epitaxy). TBAs-, H2-, and TBP-flushing were carried out with various flushing times after the growth of the GaInAs layers. The CTR analysis showed the desorption lifetimes of As in TBAs, H2, and TBP atmosphere are about 23, 22, and 6 s, respectively.
