若丹菁染料键合于单晶锗表面的研究

A studies on the rhodacyanines photosensitive dyes binding to monocrystalline germanium surface

将两种若丹菁染料直接键合在抛光的单晶锗表面 ,对键合有若丹菁的锗片进行了激光 Ra-man光谱及 XPS谱分析 ,结果表明 ,两种染料通过锗氧键共价键合于锗表面。键合有染料的 n-型锗片的 In( Pt) /染料 /n- Ge器件具有整流作用。

A new chemical method was set forth. Two rhodacyanines were bound covalently on the polished surface of Monocrystalline germanium .The Raman spectra and XPS showed that the two Photosensitive dyes were bound to the germanium surface through Ge-O bond . The photosensitive dyes binding germanium wafers In /dye /n Ge had the rectified character.
