从扫描隧道显微镜(STM)的工作原理出发,分析了STM图象畸变产生的原因,建立了一种相应的物理数学模型。利用计算机通过数值解,校正了STM畸变图象,并得到了满意的效果。
Based on the working principle of scanning tunneling microscope (STM), the causes of distortion in STM image are analyzed and a corresponding physical mathematical model is established. By using computer numerical solution, the image of STM distortion is corrected and satisfactory results are obtained.
