报告摘要:Future technologies will require new paradigms in design, functionality, scalability and a reduction in power consumption to meet our global energy challenges. Hybrid inorganic-organic systems (HIOS) offer a promising route because they may combine the best features of two distinct material classes or even achieve entirely new synergies. My group is developing quantum mechanical techniques (e.g. density-functional theory and Green’s function methods) and computer programs to describe such hybrid systems .The atomistic insight helps us to reach a quantum mechanical understanding of hybrid systems and to improve their properties for future devices. In this presentation, I will first address the structure and morphology at C60/TiO2 interfaces. Then, I will address charge carrier dynamics[1]. Last, I will address the question whether charge at organicinorganic interfaces transfers to a molecule as a whole unit (integer charge transfer (ICT)) or resides on several molecules simultaneously (partial charge transfer (PCT))[2].
