本文是探讨扫描电子显微镜中一种新的成象模式。根据日1所示的实验方法:我们得到了所观察试样的图象(图2)。通过各种实验,我们认为这种成象模式,是利用样品表面电子电荷变化的信号,通过电容效应,在探测器的PN结上感生出相应变化的电动势。这电动势经放大后在CRT上显示出了试样表面的形貌象。我们称这成象 This article is to explore a new imaging mode in scanning electron microscopy. According to the experimental method shown in Day 1: we obtained the image of the observed sample (Figure 2). Through various experiments, we think this imaging mode utilizes the signal of the change of electron charge on the surface of the sample to induce a correspondingly varying electromotive force on the PN junction of the detector through the capacitance effect. This electromotive force is magnified on the CRT showed the appearance of the sample surface. We call this image
