How Do Dual Beam Systems Work?
The SEM component utilizes a beam of
electrons to scan the surface of a sample, providing high-resolution images. The FIB, on the other hand, uses a beam of
ions (typically gallium ions) to mill, deposit, or modify the material. The integration of these two techniques allows for precise, real-time observation and manipulation of nanostructures.
Applications in Nanotechnology
Dual beam systems are pivotal in various fields within nanotechnology:
Advantages of Dual Beam Systems
