FE SEM + EDS (CRF Adopted Facility)
  • About instrument

    The Central Research Facility at IIT Delhi is established for the purpose of enhancing the research ability of researchers by providing expensive analytical instruments as shared facility and for providing support for carrying out specialized analysis of samples of various kinds. Our aim is to facilitate research and technology development in the area of advanced materials, and thus, offer state-of-the-art characterization facilities. Proper and reliable characterization is an important aspect in any research work. Three instruments from SMITA Research Lab are being offered under CRF. These are Field Emission Scanning Electron Microscope (FE SEM), Micro Raman, and Nuclear Magnetic Resonance (NMR) Spectrometer.

    Field Emission Scanning Electron Microscope (FESEM) with Oxford-EDX system IE 250 X Max 80
    Name of Instrument: Field Emission Scanning Electron Microscope
    Model: FEI Quanta 200 F SEM
    Company Name: FEI Company (Netherland)
    The Quanta 200 FEG Scanning Electron Microscope (SEM) is a type of electron microscope that images the sample surface by scanning it with high-energy beam of electrons in a raster scan pattern enabling the investigation of conductive, non-conductive and high-vacuum incompatible materials. It offers nanometer resolution and a high signal to noise ratio in both regular high vacuum and environmental modes. The EDS consists latest 80 mm2 SDD detector enables detection of elements under high resolution.
    Capability: • Three modes of operation can be studied in The Quanta 200 FEG SEM i.e. High vacuum (with coating mode), Low Vacuum (without coating mode), Environmental SEM and Scanning Transmission electron Microscopy.
    • Quanta FEG 200 comprises of different types like ETD (Everhart-Thornley detector), Backscattered Electrons Detector (BSED), Large Field Detector (LFD), and Gaseous Secondary Electron Detector (GSED).
    • STEM (Scanning Transmission Electron Microscopy) is also possible to form atomic resolution images and high contrast imaging of biological samples. • Surface morphology of all kinds of conductive and non conductive samples can be analyzed.
    • Texture information by performing phase identification and orientation mapping can be done by EDS.
  • Samples

    Because SEM utilizes vacuum conditions and uses electron beam to form an image, special sample preparations is needed as listed below:-
    • The sample is mounted on carbon tape that is put on the surface of the stub.
    • Approximate size of the sample 1 x 1 cm (max).
    • All water must be removed from the samples because the water would vaporize in the vacuum.
    • Electrically conductive samples do not require any preparation before being used, however the samples must be completely dry and free from volatile substances.
    • Non-conductive samples need to be made conductive by coating the sample (using sputter coater) with a thin layer of conductive material like Au/Ag/C. • For STEM mode, sample needs to be prepared on TEM grid.
    • In case of liquid sample, put a small drop of sample on TEM grid and dry it.
    • For solid sample, small amount is put on TEM grid.
