【摘要】 用STM针尖对有机络合物电双稳薄膜材料施加强电场作用 ,可在材料表面产生纳米线度的导电几何图形。实验证明 :对针尖本身的几何构形、施加在针尖上的脉冲幅度、周期和占空比都必须进行细致的选择。用Ag TCNQ络合物进行实验 ,在适合的针尖 样品距离下 ,发现所加脉冲偏压的极性为负时 ,容易进行加工更多还原

【Abstract】 Nanometer scale conductive patterns have been produced on thin films of electrical bistable organic complexes using the tip of scanning tunneling microscope (STM) with intense electric fields.Experiments showed that the STM tip should be carefully prepared.Fabrication of nanometer scale patterns on a flat surface of Ag TCNQ was realized when we chose the appropriate bias voltage,pulse height and duration of negative voltage pulses and suitable distance between tip and sample before processing.更多还原
