ERA NANOSCI: Engineering Light Induced CHarge Transfer: a first step towards inorganic photosyntesis

本项目的范围是设计新的纳米尺度结构(同轴-纳米线CNW)，能够模拟光合作用有机体收集阳光并将其能量转化为更有用的形式的过程。在对界面和载流子在纳米结构中的限制效应进行理论描述的基础上，将同时考虑无机和混合(有机/无机)天线系统，以获得更大的设计灵活性，并优化能量增益效率。我们提出的新型纳米对象由嵌入在InxGal-xN壳层中的氮化铟纳米棒组成，或者通过光吸附分子来功能化。碳纳米管结构的设计、外壳成分和特定的内碳纳米管尺寸是实现控制以优化光转换结构效率的关键因素。将对单个CNW进行结构、光学和电学表征。

The scope of the present project is to devise new nanoscale architectures (coaxial-nanowires cNW) able to mimic the processes by which the photosynthetic organism harvest sunlight and convert its energy to more useful forms. Based on a theoretical description of the interface and the confinement effects of charge carriers in the nanostructure, both inorganic and hybrid (organic/inorganic) antenna systems will be considered, to get larger flexibility on the design, and optimize efficiency in energy gain. The novel nano-object that we propose consists of an indium nitride nanorod either embedded in an InxGal-xN shell or functionalised with a light adsorbing molecules. The design of the cNW structure, the outer shell composition, and the specific inner NW size are the key elements on which it is required to achieve control to optimize the structure efficiency for light conversion. Structural, optical and electrical characterization will be performed on the single cNW.
