title: Nano-Floating Gate Memory Devices Composed of ZnO Thin-Film Transistors on Flexible Plastics.
abstract: Nano-floating gate memory devices were fabricated on a flexible plastic substrate by a low-temperature fabrication process. The memory characteristics of ZnO-based thin-film transistors with Al nanoparticles embedded in the gate oxides were investigated in this study. Their electron mobility was found to be 0.18 cm(2)/V·s and their on/off ratio was in the range of 10(4)-10(5). The threshold voltages of the programmed and erased states were negligibly changed up to 10(3) cycles. The flexibility, memory properties, and low-temperature fabrication of the nano-floating gate memory devices described herein suggest that they have potential applications for future flexible integrated electronics.
