【 摘 要 】

This research project is focused on (1) development of novel scanning probe microscopy techniques for investigation of the thermally and electrically induced changes in the physical properties of organic polymer ferroelectrics; (2) fabrication of ferroelectric nanostructures and investigation of their functional behavior; (3) fabrication and testing of the organic photovoltaic devices with enhanced energy conversion efficiency. Research activities throughout this project resulted in novel effects and exciting physics reported in 10 papers published in high-profile journals, including Nature Materials, Nano Letters, Advanced Materials, Energy and Environmental Science and Applied Physics Letters. These findings have been presented at a number of domestic and international conferences such as MRS Spring and Fall meetings, International Symposium on Integrated Functionalities, International Symposium on Applications of Ferroelectrics (in total 9 presentations). Below we summarize the most important findings of this project.
