How Do These Techniques Differ in Terms of Resolution and Applications?
- SEM offers high resolution (1-10 nm) and is excellent for imaging surface features. It is widely used in materials science and engineering.
- TEM provides the highest resolution (0.1-2 nm) and is ideal for studying the internal structure of nanomaterials, such as nanoparticles and thin films.
- AFM offers good resolution (1-10 nm) and can image non-conductive samples. It is used in various fields, including biology, for imaging cells and biomolecules.
- STM provides atomic-level resolution (0.1 nm) and is used for imaging and manipulating individual atoms and molecules on conductive surfaces.
