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.

卷起的半导体纳米管（RUNTs）将被精确地定位在衬底表面上，随后被用作纳米反应器来局部合成新型混合材料。定位过程的RUNTS结合自组织和光刻，并将作为各种工艺参数，如蚀刻时间和层厚度的函数进行研究。我们打算用聚焦激光局部加热单个和位置良好的RUNTs，并用显微拉曼光谱原位监测横向调制混合材料的局部化学合成。将通过显微光致发光、透射以及扫描隧道显微镜进行非原位表征。
