The methods of purification and single crystal growth of six II – V semiconducting compounds are discussed and crystallographic data are presented. The six compounds, representing three stoichiometries, are , , , , , and . The compounds are thermally dissociated in the vapor phase, and the solid‐vapor equilibria of four of the compounds has been measured. Because of the thermal instability, crystal pulling was carried out in sealed quartz tubes employing magnetic suspension of the seed. Through purification of the elements and single crystal growth, high purity was attained in most of the compounds. The highest purity is represented in with an electron carrier concentration of .
