| Popis: | 102 With the development of electrical technology, flexible electronics attracts attention in marketplace. Their flexible capability promotes different applications to electrical products, such as flexible displays, electronic papers, organic solar cells and RFID tags. In all these applications, organic thin film transistors (OTFT) are one of the most important elements. In last ten years, researches on p-type organic semiconductor have been extensively developed. On the other hand, the development of n-type organic semiconductor is still limited. Therefore, it is important to fabricate the n-type organic semiconductor for the complementary circuit technology. In this work, we used an inkjet printing fabrication system which was made by our research team to develop n-type OTFT, The n-type organic semiconductor P (NDI2OD-T2) was used as the channel material in our devices. Based on these technologies and materials, we successfully fabricated n-type OTFT devices. The device with Au contacts and polymer dielectric, achieved the mobility up to 0.3 cm2V-1s-1 and on/off current ratio of 3.4 x 103. Besides, the device with printed PEDOT: PSS electrode achieved the mobility up to 0.022 cm2V-1s-1 and on/off current ratio of 6.8 x 102. Based on this development, we will be able to fabricate all-inkjet-printed complementary organic circuits for future applications. |
