C_（70）在GaAs电极上的光电性能研究

Abstract

在光电化学电池中测定C＿（70）球烯在gAAS电极上所形成异质结的光伏效应，并研究不同介质电对和C＿（70）薄膜厚度对光伏效应的影响。结果表明，1）I＿2/是较佳的介质电对；2）C＿（70）薄膜厚度约为1μM时光伏效应较大；3）C＿（70）在gAAS电极上的光电性能是优良的。

The photovoltaic eFFect(PVE ) Forheterojunction Formed by C_(70)on GaAs electrode inthe photoelectrochemical cell was investigated.In Fluences of various redox couples and of thicknessof C_(70)on the photovoltaic eFFect were observed.Theresults showed that:1)I_2/was the best redoxcouple in the photoelectrochemical cell.2)Thephotovoltaic property of C_(70)-GaAs electrode at 1μmFor thickness of C_(70) was best.3 ) The photoelectricproperty of C_(70) on GaAs electrode was excellent.
