ABSTRACT
We have fabricated cross-junction devices by means of a soft contacting of multi walled carbon nano-tubes (MWNTs) and have studied low-temperature transport in the nano-space formed by their crossing. In two-terminal resistance measurements, made using the diagonal and off diagonal configurations of the device, this transport is characterized by a power-law dependence as expected for Tomonaga-Luttinger liquids (TLLs) has been observed. Four-terminal measurements, however, show no TLL behavior, but rather metallic transport that is corrected by weak localization in the case where a good contact is formed to the cross-junction.
