Cel projektu 

The main goal of this research proposal is to develop a novel “e-beam-driven nanoengineering“ synthesis method to achieve the growth of SWCNTs with well-defined chirality, i.e. control over their electrical properties (semiconducting or metallic). Furthermore, the proposed technique confers a high degree of spatial control over the growth location of the SWCNTs, which is a crucial advantage over conventional chemical vapor deposition (CVD) methods. The characteristics of the synthesis technique make it possible to pursue several secondary goals. The synthesis process is mainly intended to be performed fully at room temperature inside a transmission electron  microscope (TEM) using Au nanoparticles as catalyst material, although, a heating stage can be used if necessary. Therefore, one could directly observe the growth dynamics in real-time, thus, advancing our understanding of the growth of SWCNTs from metallic nanoparticles at an atomic level. The exploration of self-assembly processes instigated by fundamental interactions between an electron beam and a solid precursor is a key step towards extending the sub-field of e-beam-driven chemistry and nanoengineering techniques.
