单晶硅表面键合复合份菁及其伏－安特性

The Bonding of Merocyanines to Monocrystalline Silicon Surface and Their V-Ⅰ Character

用化学方法将３种复合份菁化学键合于单晶硅表面，并用激光拉曼光谱和Ｘ－光电子能谱进行了表征。暗的和光照的伏安特性测量表明键合染料的ｎ—Ｓｉ表面具有光生伏特效应，证实了ｎ－Ｓｉ－侧存在电子势垒。

It is reported that the merocyanines were bound to monocrystalline silicon surface through chemical way.Then the silicon wafer binding photosensitive dyes was characterized by SERS & XPS.Their Ⅰ-Ⅴ curves indicated that the In/dye/n -Si have photovoltaic effect.
