摘要： 本文制备了PANI纳米点阵列, 利用导电原子力显微镜(C-AFM)表征了其形貌和导电性能, 在室温下观察到PANI纳米点的库仑台阶(Coulomb staircase)现象, 并利用库仑阻塞效应的理论进行了初步的分析.

关键词: 聚苯胺(PANI), 纳米点, 库仑台阶, 导电原子力显微镜(C-AFM)

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)
