Scanning electron microscopy (SEM) imaging is a powerful technique used in materials science, biology, and other scientific fields to visualize the surface of a sample at nanoscale resolution. In SEM imaging, a focused beam of electrons scans the surface of the sample, generating high-resolution images that reveal details of the sample's topography, morphology, and composition. SEM imaging can provide valuable information about the structure and properties of materials, biological samples, and other objects, making it a versatile tool for scientific research and analysis.
