Room temperature HgI₂ nuclear radiation detector

Room temperature HgI 2 nuclear radiation detector 1 first-author 1 1 1 1 1 2 2 2 Materials Science Department, Sichuan University, Chengdu 610064 Materials Science Department, Sichuan University, Chengdu 610064 Institute of Nuclear Science Technology, Sichuan University, Chengdu 610064 Institute of Nuclear Science Technology, Sichuan University, Chengdu 610064 Room temperature radiation detectors are fabricated from large HgI 2 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 (10 2 ~10 4 cm -2 ), and the detectors fabricated from the crystals exhibit good energy resolution and very slight polarization.
