Introduction In electron beam (E-beam) evaporation, the crucible is far more than a simple container—it directly influences thermal stability, evaporation efficiency, and thin film purity. Selecting the right crucible material is critical, especially in high-vacuum and high-temperature environments used in semiconductor fabrication, optical coatings, and advanced research. Among refractory metals, molybdenum (Mo) and tungsten (W) […]
