Abstract:

This is a productive research project 12 papers in three years aiming to understand the potential of conjugated polymer in a wide range of organic electronic devices - vertical transistors,solar cells and photodetectors, memory devices, as well as graphene. We demonstrate both evaporated small molecule and solution process polymeric vertical organic transistors in the project through nanoscale interface engineering. X-ray radiation degradation and recovery of polymer solar cell is observed and is encouraging for OPV application in space. Photomultiplication with high EQE is achieved by introducing interface carrier traps in both small molecule and polymer DA systems, which has high potential for detector application. Working mechanism of organic memory devices is studied. Also we showed high quality transparent conductor based on chemically converted graphene and CNT composite. An easy transfer process is also developed to facilitate the application of graphene transparent electrodes.
