The chemical composition of the Al2O3 was confirmed from the X-ray photoelectron spectroscopy analysis. The capacitance-voltage (C-V) characteristic of Al/Al2O3/Si (MOS) metal-oxide-semiconductor structure showed clear accumulation, depletion and inversion regions as-compared with the Al/SiNx/Si MOS devices, respectively, From the C-V curves, the flat band voltage(ΔFB) was shifted accordingly positive and negative with respect to electron/hole trapping effect. In addition, 10 nm AlOx storage layer and SiNx storage layer were compared in the same structure. The 10 nm SiNx storage layer showed a very low retention of 55.1% and the memory window also showed a relatively low value of 2.72V at 18V.","PeriodicalId":129222,"journal":{"name":"2019 26th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122315058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show the advantage of iOLEDs over the conventional OLEDs from the fact that the luminance of a conventional-OLED-based flexible display decreases rapidly, whereas our iOLED-based flexible display exhibits approximately half of its initial luminance even after about 392 d. Electrons are injected into iOLEDs effectively by utilizing the solution process and a suitable dopant that can reduce the surface work function.","PeriodicalId":129222,"journal":{"name":"2019 26th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133093241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, hybrid material containing high-k BaTiO3 nanoparticles and transparent Poly-siloxane (Poly-SX) were used as gate insulator in a-IGZO TFTs. Opting for a hybrid material instead of only a BaTiO3 film enables lowering of process temperatures. This paper presents the performance of a-IGZO TFTs with solution processed hybrid gate insulators at different BaTiO3/Poly-SX ratios deposited at a lower temperature (300°C).
