 The technique of focused electron beam induced deposition, FEBID, has been developed significantly over the past 20 years, allowing for the fabrication of nanostructures with high precision and control. FEBID has become a powerful tool for researchers in many different fields, including material science, physics, and engineering. Recent applications include the fabrication of strain-sensitive and magnetic field-sensitive devices, as well as the creation of complex nanoscale composites.
