HgCdTe表面钝化——阳极氟化的初步研究

INVESTIGATION OF HgCdTe SURFACE PASSIVATION──PBELIMINARY STUDY OF ANODIC FLUORIDIZATION PROCESS

  • 摘要: 本文尝试采用非含水的NH4F或KF以及含水的KF电解质溶液对Hg1-xCdxTe(x=0.2)表面的阳极氟化进行了研究,着重分析了阳极氟化膜生长的基本过程及其机理,讨论了阳极氟化条件及工艺对薄膜组成及质量的影响。

     

    Abstract: A novel anodic fluoridization process using nonaqueous NH4 F or KF and/or aqueous KF electrolute for forming native fluoride films on Hg1-xCdxTe (x=0.2)is described. The principal anodic fluoridization process and its mechanism are analyzed with emphasis. The effect of the growth condition on the film composition and quality is discussed.
