3N5 (99.95%) Germanium (Ge) Pieces Evaporation Materials
Introduction:
Germanium evaporation materials refer to solid substances primarily composed of germanium (Ge), specifically engineered for use in thermal evaporation processes. These materials are typically in the form of pellets, rods, wires, or sheets, suitable for vaporization in vacuum environments.
During the thermal evaporation process, the solid germanium material is heated to its vaporization temperature, causing it to transition directly from a solid to a vapor state. The vaporized germanium then condenses onto a substrate surface, forming thin films or coatings with desired properties.
Germanium evaporation materials find applications in various industries due to germanium’s unique properties, such as its high refractive index, excellent infrared transmission, and semiconductor properties. They are commonly used in the production of thin films for optical coatings, infrared sensors, and semiconductor devices.
