- Abstract
- The electrical bistabilities of core/shell CdSe/ZnS nanoparticles embedded in polystyrene (PS) and poly(4-vinylphenol) (PVP) hybrid polymer composites were investigated. Transmission electron microscopy images showed that CdSe/ZnS nanoparticles were formed inside the hybrid polymer matrix. Current-voltage (I-V) measurement at 300 K of Al/(PS + PVP)/(CdSe/ZnS nanoparticles)/(PS + PVP)/ indium-tin oxide/glass devices showed electrical bistability behavior. The memory mechanisms of the organic bistable devices fabricated utilizing CdSe/ZnS nanoparticles embedded in hybrid polymer composites are described on the basis of the I-V results.
