Abstract
Organic bistable devices (OBDs) based on nanocomposites consisting of C-60 embedded in the poly(methyl methacrylate) (PMMA) layer were fabricated by using a spin coating method. The current density-voltage (J-V) curves of the Al/C-60 embedded in PMMA layer/indium-tin-oxide devices exhibited an electrical bistability with a low-conductivity state, a transition state, and a high-conductivity state. The J-V curves for OBDs containing hybrid C-60 and PMMA except a low voltage range were reasonably fitted by using the space-charge-limited current conduction model. The trapped electron densities of the OBDs were attributed to the space charge relative to the internal electric field. (C) 2012 The Japan Society of Applied Physics
