TEM images of the Ti/Au-nanotube contact interface.

These images show the interface of the Ti/Au contact covered nanotube to the bare nanotube. The shadow created by the mask is almost line-of-sight, but there is a small transition region. From these images, it appears that the nanotube remains undamaged by the evaporation process. These TEM images show that the nanotube is contacted along it's length. This "bulk" or "side" contact plays an important role in determining the conductance of the nanotube.
