实现了在等离子体增强化学气相沉积工艺期间催化生长的碳纳米纤维（CNF）以可变角度相对于基底的受控对准。在合成过程中，通过电场线的方向来控制CNF的取向。通过将样品定位在样品保持器的几何特征附近来实现偏离正常的CNF取向，其中电场线发生弯曲。扭结的CNFs，由两个部分组成，在不同的角度对准基板正常的控制增长也被证明。(C)2002年美国物理学会。
Controlled alignment of catalytically grown carbon nanofibers (CNFs) at a variable angle to the substrate during a plasma-enhanced chemical vapor deposition process is achieved. The CNF alignment is controlled by the direction of the electric field lines during the synthesis process. Off normal CNF orientations are achieved by positioning the sample in the vicinity of geometrical features of the sample holder, where bending of the electric field lines occurs. The controlled growth of kinked CNFs that consist of two parts aligned at different angles to the substrate normal also is demonstrated. (C) 2002 American Institute of Physics.
