Abstract
Our group has improved the property of the space-charge-limited transistor for many years. To drive the organic light-emitting device (OLED) and E-paper by SCLT and commercialize all of this application, lifetime and the stability are the main bottleneck of the development. Without being encapsulated, the electricity of the SCLT would decrease day by day because of the moisture. Therefore, maintaining the life time of the SCLT is to develop the well encapsulation. Due to simulating the reality of the commercialized product of SCLT, we will operate the device for a long time and then calculate the value of the threshold voltage which affects the SCLT driving the OLED and E-paper. Decreasing the threshold voltage, the process of the SCLT would be improved. The main ideas of this dissertation are to investigate the lifetime of SCLT after encapsulated and the stability of SCLT by adding self-assembled mono-layer or irradiating UV Ozone process which improves the fabrication process.
