Scanning electron microscopy (SEM)

The scanning electron microscope allows different analysis methods. At this point we want to focus on the microscopy mode as method for analysis. We use an Evo 15 (Zeiss) which allows to resolve structures down to 5 nm with a magnification up to 300 000 times due to the small wavelength. Additionally, to the high magnification, this system offers an increased depth of field, compared with similar devices.
