SVT Associates offers a wide selection of Effusion Cells (aka Knudsen cells or k-cells) to create a vapor source from many elemental or compound materials. Each Effusion Cell is manufactured from high purity components with all ceramic and refractory metal hot zones. This ensures no undesired outgassing in a UHV environment as well as promotes the longevity of the cells.
The Effusion Cell is a highly controllable and efficient deposition source for MBE and non-epitaxial Physical Vapor Deposition. The radiatively heated crucible with a close coupled thermocouple ensures stability and reproducibility not found with other evaporation sources. The optimally shaped crucible increases material utilization.
