Position-controlled semiconductor nanotubes as templates for novel hybrid nanomaterials

卷起的半导体纳米管将被精确地定位在衬底表面，随后被用作纳米反应器来局部合成新型杂化材料。Runts的定位过程结合了自组织和光刻技术，并将作为各种工艺参数的函数进行研究，例如蚀刻时间和层厚度。我们打算用聚焦激光对单个和位置良好的矮子进行局部加热，并用显微拉曼光谱原位监测横向调制杂化材料的局部化学合成。非原位表征将通过显微光致发光、透射式和扫描隧道显微镜进行。

Rolled-up semiconductor nanotubes (RUNTs) will be accurately positioned on a substrate surface and subsequently exploited as nanoreactors to locally synthesise novel hybrid materials. The positioning process of the RUNTS combines self-organisation and lithography and will be studied as a function of various process parameters such as etching time and layer thicknesses. We intend to locally heat individual and well-positioned RUNTs with focussed laser light and the local chemical synthesis of laterally modulated hybrid materials will be monitored in-situ with micro-Raman spectroscopy. Ex-situ characterisation will be carried out by means of micro-photoluminescence, transmission as well as scanning tunnelling microscopy.
