Growth and Characterization of InGaAsSb on InP Substrate by Molecular Beam Epitaxy
the InGaAsSb epilayers were grown on InP substrate
the reflection high-energy electron diffraction(RHEED) was used for in-situ monitoring InGaAsSb surface morphology. We systematically studied the effect of the growth temperature and Ⅴ/Ⅲ ratio on a serious of heteroepitaxial quality InGaAsSb films.Optimized the growth-temperature
the epilayers were performed at maintaining binary growth in the cases of 350 ℃
and the folllowing higher quality film appears at 400 ℃.The epitaxial thin films characterization were presented and analyzed
such as surface morphology
interface inspection
crystalline quality and photoluminecence characteristic by scanning electron microscopy (SEM)
X-ray photoelectron spectrum (XPS)
X-ray double-crystal diffraction (XRDCD) and photoluminecence (PL)
etc.
We also showed some questions about the growth temperature and Ⅴ/Ⅲ ratio. In conclusions
the high quality InGaAsSb epilayers with optimized growth temperature and Ⅴ/Ⅲ ratio were obtained
which exhibits a XRD peak with narrow full-width at half maximum (FWHM).
