SEM specimens

SEM specimens refer to materials prepared for analysis using a Scanning Electron Microscope (SEM), a powerful tool that allows scientists to view the fine details of surfaces at a microscopic level. To create SEM specimens, samples are typically coated with a thin layer of conductive material (like gold) to prevent charging during imaging. This preparation allows the SEM to produce detailed, high-resolution images of the specimen’s surface topography and composition, revealing structures and features that are not visible to the naked eye. SEM is widely used in materials science, biology, and electronics for research and quality control.
