Description
The Viking Series Effusion Cell is designed for highest quality growth of Gallium or Indium-containing III-V compounds. The proprietary design maximizes capacity, while increasing uniformity and long term flux stability. The Viking is ideal for long growth campaigns and epitaxial structures requiring abrupt interfaces. The design eliminates shutter transient and “spitting” experienced with other effusion cells. With a fully enclosed filament, the Viking is compatible with corrosive environments such as ammonia and oxygen backgrounds. The innovative shaped crucibles provide high flux stability, while remaining simple to load material.
