This lecture covers advanced scanning electron microscope (SEM) technologies, including low voltage imaging, high-resolution SEM, and examples of SEM applications. Topics include in-column detectors, plasma cleaning, polishing techniques, and the latest generation environmental SEM. The lecture also discusses the use of field emission guns, monochromators, and beam boosters for high-resolution imaging. Additionally, it explores the analytical capabilities of SEM, such as energy-dispersive X-ray (EDX) detectors and electron backscatter diffraction (EBSD) detectors. Various examples demonstrate the practical applications of SEM in materials science and nanotechnology.
