Ga0.51In0.49P的MOCVD生长特性研究
THE GROWTH CHARACTERISTIC STUDY OF Ga0.51In0.49P BY MOCVD
【摘要】 本文报导了用国产常压MOCVD系统生长GaInP材料.研究GaInP的生长特性,用光致发光、扫描电镜、X光双晶衍射对材料进行表征.发现Ⅴ/Ⅲ比对GaInP的光学特性有很大影响.在温度680℃,Ⅴ/Ⅲ比为90的条件下得到Ga(0.51)In(0.49)P外延层的光致发光谱的半高宽为26meV,这是目前报导的最好结果.Ga(0.51)In(0.49)P的本征载流子浓度为1.1×10(15)cm(-3),晶格失配为4×10(-4).
【Abstract】 GaInP have been. grown on GaAs substrates by metalorganic chemical vapor deposition(MOCVD) in a horizontal, atmospheric pressure reactor. The growth characteristic of GaInP wes studied by PL measurement, SEM, X-ray double crystal diffraction.Ⅴ/Ⅲ ratio influenced the optics quality of GaInP. Featureless surface morphologies Ga0.51In0.49P were obtained. At a Ⅴ/Ⅲ ratio of 90, temperature was 680℃, the epilayer had photoluminescence(PL) FWHM of 2 6 meV at 300 K, the best reported results to date. The background carrier concentration of Ga0.51In0.49P was 1. I × 1015cm-3. The mismatch of Ga0.51In0.49P was 4 × 10-4.
