Al/CdO:TiO2/p-Si/Al heterojunction devices exhibited optoelectronic device behavior due to their photocurrent under solar light illuminations. The photoresponse behavior of the diodes is controlled by changing the molar ratio of CdO to TiO2. The fabricated CdO:TiO2 (2:1) based device exhibited the highest photoresponse of about 7.5 x 10(3). The interface properties of the devices are changed with the molar ratio of CdO:TiO2. The obtained results suggest that CdO:TiO2 composite film/p-type Si structure can be used in optoelectronic applications.eninfo:eu-repo/semantics/closedAccessElectrical propertiesphotodiodeCdO:TiO2 compositeillumination effectinterfacial layerArticle47127159716910.1007/s11664-018-6647-12-s2.0-85053407945Q2WOS:000448979100024Q3
