Fig. 2: Characterization of individual carbon nanotube.
From: Enhanced osmotic transport in individual double-walled carbon nanotube
a AFM scan image of a single CNT. Scale bar: 100 nm. b TEM image shows that the single CNT is a double-walled tube with an outer diameter of 5.3 nm and an inner diameter of 4.6 nm. Scale bar: 5 nm. c The cross-section corresponding to the position of the dashed line in (a) shows that the outer diameter of the CNT is about 6 nm. d Raman spectrum of the carbon nanotube, the disappearance of the D peak shows that there is no defect, and the shape of the G peak indicates that this carbon nanotube belongs to a semiconductor tube34,35. Source data of (c, d) are provided as a Source Data file.
