Tunable Electrical Memory Behaviors of Carbazole containing Diblock Copolymers by Different Film Morphology |
| 초록 |
The linear-brush diblock copolymers bearing carbazole moieties were synthesized with reasonable molecular weight. The various nanostructures were found to develop in nanoscale thin films, depending on the fabrication conditions including selective solvent-annealing. The developed nanostructures were observed using grazing incidence X-ray scattering measurement and then quantitatively analyzed. Overall, the relationship between the morphology and electrical memory performance of these copolymers has several important features. In particular, the carbazole moieties in the vertical cylinder phase with a radius of 8 nm or less can trap charges and also form local hopping paths for charge transport, which opens the mass production of advanced electrical memory devices with ultrahigh memory density. All the observed memory behaviors are governed by the trap-limited space-charge-limited conduction mechanism and local hopping path formation. |
