![]() Principle: Thermal evaporation is a method of heating the evaporating material through the evaporation boat with a large current under vacuum conditions, so that it melts and evaporates or sublimates at high temperature, and the vaporized material is transported to the substrate and condenses to form a film on the substrate. By adjusting the size of the applied current, the evaporation rate of the coating material can be easily controlled. It is usually suitable for the preparation of metal films with melting point below 1500℃. |
