Reduction and correction of sample surface charging effects in scanning electron microscopy imaging

Scanning electron microscopy (SEM) is a powerful imaging technique capable of providing high-resolution images of the sample surface. However, the charging effect on the sample surface often leads to image distortion and noise, which affects the imaging quality of the SEM. In this article, we will describe some common methods to reduce or correct the surface charging effect of the sample, thereby improving the accuracy and reliability of SEM imaging.

Does the Electron Beam in Scanning Electron Microscopy Cause Damage to the Sample?

A scanning electron microscope (SEM) is a high-resolution microscope used to observe and analyze the surface morphology and structure of solid samples. In SEM, an electron beam is focused and scanned over the surface of the sample, generating signals that correspond to the surface morphology of the sample, which can be collected by a detector and converted into an image. Does the electron beam in SEM damage the sample
