| Outline of Final Research Achievements |
Organic Position-Sensitive devices are expected to be the optical image sensor on a flexible substrate, and they have been studied for their high sensitivity high accuracy. In our experiment, the position detection sensor is prepared with a copper phthalocyanine CuPc: fullerene C60 bulk-heterostructure having sensitivity to red light, and we report the characteristics of the device with invertied structure using Al-doped ZnO (ZnO:Al). We fabricated one-dimensional inverted structure organic position sensitive detectors, and we investigated the measurement linearity of the devices with the recombination loss model in the interface between the resistive layer and active layer. Although low linearity of the measurement accuracy by the charge traps and recombines to be taken out to the output electrodes has been a major issue for practical use, we report that a maximum measurement error has been improved by increasing the sensitivity of the active layer.
