The self-moving convection shield was used in the growth of ZnSe single cry
stal by chemical vapor transport method using iodine as a transport agent.
The reduction of the convection enables the growth of a 1-in diameter ZnSe
single crystal. The incorporation efficiency of iodine on (1 1 1)B facet wa
s proved re be larger than that on (1 0 0) facet. Impurity-hardening effect
of incorporated iodine in the grown ZnSe crystal is also suggested. (C) 19
