Teaching & Research

Gatan's Digital Micrograph is one of the most commonly used software to acquire and process TEM images. While there are many useful open source scripts created by experts all around the world, there are also equally useful open source software available for all kinds of image processing, spectroscopy and relevant analysis.

Course Contents: Introduction to EM, the necessity of characterisation using TEM techniques, brief introduction to crystallography, thinking in reciprocal space, TEM imaging and diffraction techniques (only limited to techniques available with us). - Specimen Preparation techniques (twin jet polishing and ion milling, basic drop casting) - TEM imaging, bright field and dark field - STEM imaging - Diffraction, reconstruction of unit cell and analysis - Indexing diffraction patterns - Analytical TEM techniques, EDX - Practical sessions will be such that the students will be able to operate the microscope, carry out basic imaging, diffraction (BF/DF) and construct a unit-cell from diffraction patterns as well as carry out basic STEM-EDX analysis.
