Outline of Final Research Achievements

The ultimate goal of this research is to improve the flexibility of organic EL displays and organic semiconductors used in wearable computers, flexible televisions and the like. So far, organic thin films have been thought to be rich in flexibility, but we have reported that there are fragile materials at the first time in the world, and have proposed the improved device structures in which that the fragile materials are replaced with difficult-to-break materials or replaced mixed layers of fragile materials and fragile materials. In this research, (a) Performance evaluation method (device, specimen shape, temperature dependence) that measures the performance by adding distortion while emitting or operating, (b) The application of nano-indentor method to estimate the stress-strain curve of the wet process type polymeric organic EL materials and organic solar cells, were investigated .
