P-1.13: Influence of the Source/Drain Material on Oxide Semiconductor Thin Film Transistors
摘要： With the progress of technology, to reduce the load of display panels, some researchers have been carried out to investigate the effects of source/drain electrodes on the performance of a-IGZO based TFTs. In this paper, indium gallium zinc oxide (IGZO) is chosen as the active layer material, and we use four different types of source/drain materials including indium-tin-oxide (ITO), Al, Al-doped zinc oxide (AZO) and Ga-doped zinc oxide (GZO) to explore the influence of different source/drain materials on the characteristics of oxide semiconductor thin film transistors (TFT). The results show that TFTs with AZO as source/drain electrodes exhibit good characteristics. After 200℃ annealing, the output characteristic of TFT with AZO as source/drain electrodes becomes better and its source/drain series resistance is low. From this study, AZO can be considered as a hopeful source/drain material which would be utilized in the future displays technology.

All-Optical Poling and Two-Photon Absorption in Heterocyclic Azo Dyes with Different Side Groups
摘要： We investigated the optical properties of heterocyclic azo dyes with different side groups prepared: as powders, in PMMA matrix and side-chain polymers. We characterized the nonlinear optical effects of these compounds by Z-scan and all-optical poling techniques and supported these experiments with theoretical modeling. It was also found that these materials show strong two-photon absorption cross-sections exceeding 20 GM, which is one order of magnitude stronger than that of similar materials (azobenzene and p-aminoazobenzene). Our study reveals the dominant role of the side-chain system over the guest-host one and stress out the importance of the substituent in the efficiency of the poling process.
