Abstract

The organic highly conducting Langmuir-Blodgett (LB) film formed by a molecular association of BEDO-TTF and stearic acid shows the logarithmic decrease of DC conductivity and negative magnetoresistance at low temperature. These data are interpreted by the weak localization of two-dimensional (2D) electronic system inside the homogeneous conducting layer of BEDO-TTF molecules. The electronic length with phase memory has a mesoscopic scale. Strong evidence of the 2D coherent charge transport in the conducting LB film is provided for the first time.
