제목 | Effect of Au Nanocrystals Concentration on Nonvolatile Memory Characteristics for Polymer Memory-cells. |
초록 | We researched the effect of Au nanocrystals on nonvolatile memory characteristics such as memory margin, retention time, and endurance cycles of program and erase for polymer memory-cells. The advantage of polymer memory-cells is the possibility of bistable switching characteristics, the smallest device feature size of 4F2, and fast access and store times of ˜10 ns. Two-terminal electrical bistable memory-cells have been fabricated using a sandwich structure of Al ⁄ polystyrene(PS) + Au nanocrystals ⁄ Al. Au nanocrystals were prepared via chemical synthesis and mixed with PS. In our research, through the electrical measurement and high-resolution cross-sectional transmission electron microscopy (TEM), we propose that the synthesis condition of Au nanocrystals and optimal concentration is the important factor for nonvolatile memory behavior such as Vth, Vp, Ve, negative differential resistance(NDR) and enough bistability of ˜1x102, due to the uniform distribution of monolayered Au nano-crystals.
