Abstract:This study reports the investigation of the effect of cerium (Ce) dopant concentration on defect levels in Ce-doped ZnO/p-type Si (p-Si) heterojunctions (HJs) by deep-level transient spectroscopy (DLTS). Undoped ZnO (uZnO) and Ce-doped ZnO (Ce:ZnO) were synthesized at different molar ratios using the sol–gel method, and n-Ce:ZnO/p-Si heterojunctions were fabricated on p-Si via spin coating. According to energy dispersive x-ray spectroscopy (EDS) data, no foreign atoms are present in the synthesized nanoparticl… Show more
