Understanding Scanning Electron Microscopes (SEM) and Their Applications

A Scanning Electron Microscope (SEM) is a powerful imaging tool used to observe the surface morphology of materials at high magnifications. Unlike traditional optical microscopes that use light, SEM utilizes a focused beam of electrons to scan the surface of a sample, producing detailed, high-resolution images with nanoscale precision.

ZEPTOOLS - The Effect of Charge Effect in Scanning Electron Microscopy (SEM) Observation and Its Elimination

Scanning electron microscopy (SEM) is a powerful observation tool widely used in materials science, biology and other fields. However, the charge effect is a common and unpleasant phenomenon during SEM observation and can negatively affect image quality. In this article, we will introduce the formation principle of the charge effect, its effect on the image, and the effective methods to eliminate the charge effect.
