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.

本项目的范围是设计新的纳米级架构（同轴纳米线cNW），能够模拟光合生物收获阳光并将其能量转化为更有用形式的过程。基于纳米结构中的电荷载流子的界面和限制效应的理论描述，将考虑无机和混合（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物体由嵌入InxGal-xN壳中或用光吸收分子功能化的氮化铟纳米棒组成。cNW结构的设计、外壳组成和特定的内部NW尺寸是实现控制以优化光转换的结构效率所需的关键要素。将对单个cNW进行结构、光学和电气表征。
