Imaging Magnetic Materials with Helios NanoLab, Nova NanoSEM and Verios
22 Apr 2015In recent years, the race for the highest resolution in scanning electron microscopy (SEM) has been driven by nanotechnology developments, new materials and smaller devices. This application note presents recent developments that have shown that sub-nanometer resolution can be achieved when combining the monochromated electron source of the Helios NanoLab™ and Verios™ with a magnetic immersion lens system. This improvement enables similar resolution from 1 to 30 keV, meaning that operators only need to consider the information depth required, rather than limitations in resolution.

NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Electron MicroscopyElectron microscopes (EM) are used to create high-resolution images of samples at the nanoscale by means of an accelerated beam of electrons as a source of illumination. Types of electron microscope include scanning electron microscopes (SEM), transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM) and cryo-electron microscopes. Focused ion beam (FIB) microscopes are useful for modifying or milling a sample surface with nanometer precision, as well as imaging.
