Analytical Facility: Electron Microscopy Section
Overview
This Section contributes to Institute's R&D work by extending expertise and knowledge base to all researchers on materials characterization using High Resolution Electron Microscopy techniques including HRTEM, FESEM and SEM. The materials characterized include advanced ceramics, glass, composite and nanostructured materials. These advanced techniques are also extended to external users from industries, universities and other research organizations. Specific activities include characterization of surface microstructure and nanostructure of various ceramics and glass using SEM and FESEM, both fitted with EDX spectrometer, High-resolution imaging and microstructural characterization of nanostructured materials including local composition analysis down to a few nanometers size using analytical High-Resolution Transmission Electron Microscope (HRTEM) fitted with EDX spectrometer. The Section is devoted to development of functional ceramic thin films by Physical Vapour Deposition (PVD) techniques. Exploratory work on nanocomposite oxide systems by ball-milling has also been initiated.

Areas of Research
  • Development (synthesis and characterization) of ferro-electric/piezoelectric and metal oxide/nitride ceramic thin films using RF-magnetron sputter deposition technique.
  • Synthesis and characterization of nano-composite oxide systems by high-energy ball milling.
