Notes:
A method of ac dielectrophoresis was applied to align and deposit metallic multi-wallcarbon nanotubes between pre-fabricated metal (Au, Pd) electrodes with a micron scale separation.For improvement of nanotube contacts with electrodes, Ni and Pd electroless processes weredeveloped, and significant reduction of 2 terminals resistances was demonstrated. Further, usingelectron and ion beam deposited Pt contacts in two different configurations (“Pt-on-CNT” and“CNT-on-Pt”), 4 terminals measurements have been performed to evaluate intrinsic nanotuberesistances. The values between 90 and 130 kΩ/μm were obtained, while systematically lowervalues (30-70 kΩ/μm) were estimated using 2 terminals method. The 4 terminals method wasapplied to study the effect of ion irradiation on the electrical parameters of supported nanotubes
