| Abstract: | The photo-generated charges characteristics of CdS/ZnO heterostructures materials were studied by means of surface photovoltage techniques.The results show that the photovoltage intensities of CdS/ZnO heterostructures materials decrease comparing with that of CdS.From the results of transient photovoltage measurement,the photo-generated electrons of CdS can transfer to ZnO since an electric field formed on the interface between CdS and ZnO.But this field is too weak to dominate the photo-generated charges c... |
