The SEM is a remarkable technique which can offer information such as the surface morphology of a sample and also a 3D appearance of the specimen. It can offer the best resolution (2 nm at 30kV) at high magnification and also topographical details because of its great depth of field. | The SEM is a remarkable technique which can offer information such as the surface morphology of a sample and also a 3D appearance of the specimen.
