The electrical transport properties of two multiwall carbon nanotubes in a crossed geometry were studied. Each carbon nanotube exhibited differential conductance vanishing with the power of bias voltage. The power-law dependence of the differential conductance was attributed to the Tomonaga-Luttinger liquid behavior of the carbon nanotube, which is considered to be a one-dimensional conductor. The differential conductance curve of one of the two carbon nanotubes was affected significantly by constant bias voltage applied to the other carbon nanotube. The characteristic features of the change of the differential conductance curve we have observed are in good agreement with the theoretical predictions for the two crossed Tomonaga-Luttinger liquids which are expected to exhibit correlated electron transport.
