ABSTRACT:
A quartz arsenic cell having a stabilizing valve used to generate hot arsenic vapor which is flowed into liquid gallium, to provide a melt of liquid gallium arsenide from which a crystal can be pulled. The stabilizing valve prevents negative relative pressure from occurring in the quartz arsenic cell, and thus prevents the molten material from being sucked back up into the quartz arsenic cell.
