Field Emission Scanning Electron Microscopy (FESEM) is used for ultra-high-resolution surface topography analysis and nanoscale material characterization .

Key Applications:

Materials Study

• Analysis of surface morphology and microstructure 
• Grain size and phase distribution studies 
• Fracture and failure analysis of metals, ceramics, and polymers 
• Investigation of coatings and thin films  
• Characterization of nanoparticles, nanowires, nanotubes, and quantum dots 

Key Advantages of FESEM

• Very high resolution (nanometer-scale imaging)
• Greater depth of field than optical microscopy
• High-quality surface imaging
• Capability for elemental analysis when coupled with EDS/EDX detectors
