Optical properties and defects of ZnO nanorods that are modified by treatment with H2O2 and used as conductive filaments for poly(methyl methacrylate)-based resistive switching applications

The optical and structural properties of ZnO nanorods that are modified using H 2 O 2 and used as the conductive filament (CF) for poly(methyl methacrylate) (PMMA)-based resistive switching (Rs) applications are studied. ZnO nanorods are used as the CF for a PMMA-based Rs device, to determine their specific properties and to determine the effect of oxygen vacancies on the Rs performance in ZnO. The Rs performance for PMMA-based devices is affected by treatment with H 2 O 2 . An appropriate H 2 O 2 treatment time produces a significant change in the Rs performance for a PMMA/ZnO nanorod array device, because there is a change in the number of oxygen vacancies in ZnO that is treated with H 2 O 2 solution at 60 ∘ C for 60 s. This study demonstrates the operation of a PMMA-based Rs device that features a ZnO CF that undergoes treatment with H 2 O 2 .
