| 摘 要： | 原子力显微镜(AFM)有接触和轻敲两种工作方式,可以在气相和液相下工作.在液相工作状态下,浸没于水中的探针和样品表面会形成一层水化膜.在探针和样品表面形成的水化膜是否会对扫描图像产生影响以及产生何种影响是一个值得研究的问题.本文用原子力显微镜对1μm标准校正光栅在空气和水两种媒质中进行了图像扫描,扫描分别采用接触和轻敲两种工作方式.扫描图像显示,在液相工作环境中,水化膜在探针和样品表面的形成将严重影响轻敲工作方式所形成的图像,而接触方式的扫描图像基本不受影响.

| Abstract: | Atomic force microscope (AFM) can operate with contact and tapping modes, under air and water conditions. It is well known that hydration films will be formed on the surface of tip and sample after they immersed in water. So it is necessary to know the effect of hydration films on scanning images. A 1 μm standard calibration grating was used for image scanning to investigate the effect of hydration films on imaging resolution in this paper. The results show that the hydration films can greatly affect the imaging resolution for tapping mode, but no evident effect on contact mode. |
