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.
