The photoelectric properties of a-IZO TFT under monochromatic illumination with various channel width (W) and length (L) are also investigated. The responsivity (R) is found to increase with the decreasing of L and almost irrelevant to W. High $mathrm{I}_{mathrm{ph}}/mathrm{I}_{mathrm{dark}}$ ratio (3.48×105) and R (287 A/W) were achieved.

High-performance organic materials, new device architecture and advanced processing technologies are developed to emerge the development of the OLED community. It is well acknowledged that electrical processes in the OLEDs include three key steps, i.e. charge injection, charge transport, and charge recombination. In this paper, we demonstrate a quantitative approach to investigate the effects of carrier mobility of electron transporting layer (ETL) on electric field and recombination profile across the organic layers of the device using software package SETFOS. The simulation outcomes proposed that a higher electron mobility results in a wider recombination zone in the desired emissive layer (EML), while narrower in case hole mobility is comparatively higher.","PeriodicalId":221271,"journal":{"name":"2018 25th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117057233","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}
