In addition, it was confirmed that the electrical characteristics change depending on the material of each MC layer. This effect is analyzed as a phenomenon which is caused by the difference between the work function of the MC layer and the work function of the channel layer. When the work function of the MC layer is smaller than the work function of the channel layer, the electrons are injected into the channel layer from the MC layer, so that higher electrical characteristics can be obtained. As a result, the electrical characteristics can be controlled by a simple change of the MC layer, and the logic circuits such as NOT, NAND, and NOR can be simply fabricated.","PeriodicalId":221271,"journal":{"name":"2018 25th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"2 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":"129699647","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}

Accordingly, we tried to create extremely flexible conductive features that can tolerate severe mechanical stress using photonic sintering process. Additionally, based on significant differences in adhesion between light-exposed and non-exposed regions with respect to the underlying substrate, it was confmned that patterning of conductive electrodes could be easily accomplished on large area. The potential of IPL treated electronic conductive features were clearly demonstrated by fabricating various emerging devices such as a light-emitting diode circuit and a flexible transparent heater with unimpaired functionality under various deformations.
