Room temperature radiation detectors are fabricated from large HgI₂ single crystals, in which, instead of temperature oscillation method (TOM), a modified vapor growth method is applied to grow the crystals in relatively stable temperature field. The crystals grown by the modified method show lower densities of dislocation (10²~10⁴cm^-2), and the detectors fabricated from the crystals exhibit good energy resolution and very slight polarization.
