EFM phase on topography overlay of a carbon nanotube
Electric force microscopy (EFM) (top) and a current-voltage curve (bottom)
of a carbon nanotube attached
to an electrode. Since the carbon nanotube is conducting, and has continuity to ground here, the EFM phase
image shows excellent contrast. In the image, color represents the EFM phase channel, and the surface
rendered with ARgyle represents topography. Scan size 5µm x 2.5µm. Imaged with the MFP-3D AFM.
