中子辐照含氢FZ-Si的红外吸收研究

对于中子辐照的n-FZSi(H₂),利用红外吸收光谱研究了由于辐照所产生的各种与氢有关的缺陷态。在未辐照的样品和辐照的样品中分别发现了未曾报道的1992cm^{-1和1857cm-1吸收峰。对于在n-FZSi(H₂)所引起的本征吸收峰和辐照损伤吸收峰,进行了讨论和指派。2150cm-1吸收峰则被认为是由于氢施主所引起的。 关键词：}

INFRARED ABSORPTION STUDIES ON NEUTRON IRRADIATED FZ-Si CONTAINING HYDROGEN

Hydrogen related defect states generated in n-FZ Si(H₂) single crystal after neutron irradiation have been studied by IR absorption. We observed some new absorption peaks that have not yet been reported. These peaks appear at 1992cm^{-1 and 1857 cm-1 in non-irradiated and irradiated specimens respectively. All absorption peaks arising from hydrogen and hydrogen related defects of n-FZ Si(H₂) before and after neutron irradiation have been both discussed and assigned. And the 2150cm-1 absorption peak is attributed to the hydrogen donor.}
