摘要：
The transient charge technique, TCT, was used to measure the trapping levels of pure and doped HgI2 detectors over the temperature range of 170-300 K. The dopants were excess of Hg and I2, naphthalene, butane, heavy paraffins, polyethylene and polyethylene glycol. The charge carriers were induced by α particles as well as by a UV nitrogen (337 nm) pulsed laser beam. The TCT determined trapping levels are compared with levels reported in literature from other solid state measurements.
