Why sem require coating?4 answersSEM requires coating because it helps to prevent the accumulation of electric charge in nonconductive samples, allowing for smooth conductance of electron microscopic studies. Coating the sample with a thin layer of gold or gold-palladium alloy is commonly done to prevent charging of the surface, promote the emission of secondary electrons, and provide a homogeneous surface for analysis and imaging. However, coating has disadvantages such as masking tiny surface details and making the sample unsuitable for further analysis. Recent studies have shown that ionic liquids can be used as conductive coatings for biological samples, eliminating the need for fixation, dehydration, or metal coating. Coatings are also important for studying the microstructure and local phase assembly in coatings, as SEM-based diffraction techniques provide a simple method for obtaining local crystallographic information.
