Abstract: PANI nanodots array was fabricated in AAO template with potentiostatic method in a short time. The topographic image of PANI nanodots array was characterized by scanning electron microscopy(SEM) and atomic force microscopy(AFM). The I-V characteristics of conducting PANI nanodots array was measured with conducting atomic force microscope(C-AFM) in atmosphere at room temperature. Coulomb staircase phenomena was observed in the I-V curves.

Key words: Polyaniline(PANI), Nanodot, Coulomb staircase, Conducting atomic force microscope(C-AFM)
