Silicon nanoparticles (Si NPs) were synthesized by chemical oxidation and etching method and capped using alkanedienyl passivation by covalent attachment of 1,9-decadiene to form resistive switching element. The alkanedienyl passivated Si NPs were in situ copolymerized into polystyrene (PS) matrix with monomer of styrene to form a polymerized resistive switching layer consisting in structure of ITO/PS-Si NPs/Al device. Write-read-erase-read operations controlled by bias were demonstrated in the device. These results can be extended to development for very thin resistive switching device based on organic solution process. (C) 2015 Elsevier B.V. All rights reserved.
