研究目的
To develop a line-width controllable large-scale assembly of SWNTs based on aqueous solution, using electron beam (E-beam) lithography to construct self-assembled templates.
研究成果
The study successfully demonstrates a method of assembling SWNTs with different line widths using E-beam lithography, obtaining regular arrays. This method allows for the design of different line-widths SWNTs arrays according to application functions, making the assembly of SWNTs more practical.
研究不足
The method is affected by the properties of SWNTs and the efficiency and cost of E-beam lithography.
