Dear friend Nilabja Kanti Sarkar

Yes, crystallite size can also be determined by Transmission Electron Backscatter Diffraction (t-EBSD) in addition to X-ray diffraction (XRD). In t-EBSD, the crystalline structure of the material is studied using an electron beam instead of X-rays used in XRD. By measuring the intensity and width of the diffraction patterns obtained from the electron beam interacting with the sample, the size and orientation of the crystallites in the sample can be determined.

However, it should be noted that the crystallite size measured by t-EBSD may not necessarily match with the crystallite size measured by XRD, as the two techniques are based on different principles and have different resolution limits. Additionally, the choice of the technique to use for determining the crystallite size depends on several factors such as the type of material being studied, the required accuracy, and the available equipment.
