Production of Cadmium Sulfide Crystals by Coevaporation in a Vacuum

摘要

Apparatus was developed by which beams of cadmium and of sulfur were simultaneously directed to a common point on a temperature controlled substrate in a demountable vacuum apparatus. Cadmium sulfide crystals were obtained. The various types of crystals: spiroidals, globules, ribbons, and needles are described together with the conditions tending to produce each type. Crystal size can be increased by repeated exposure to the beams.
