What Does EFTEM Stand For?

EFTEM stands for Energy Filtering Transmission Electron Microscopy

EFTEM, or Energy Filtering Transmission Electron Microscopy, is a specialized imaging technique that enhances the contrast and spatial resolution of transmission electron microscopy (TEM) by filtering electrons based on their energy. This method allows for the selective observation of specific elemental and chemical information within a sample, enabling detailed analysis of materials at the atomic scale. By isolating specific energy-loss regions of the electron energy spectrum, EFTEM facilitates improved understanding of sample composition, electronic structure, and other material properties.
