Abstract
Instead of the temperature oscillation method (TOM), a modified vapor growth method was applied in this paper to grow large HgI2 crystals wi th fewer lattice defects by providing a relatively stable temperature field during growth. And a new processing technique of HgI2 crystals w as developed for detector fabrication by merging solution string-sawin g and hand-cleaving. The lattice deformations caused during cleaving w ere reduced greatly by eliminating passivated layers on the sawed crys tal platelets before cleaving.
