Abstract: | Two ways of performing the Thermally Stimulated Current (TSC) experiment have been used to investigate vapour grown HgI2:i) under light excitation, four peaks are observed at 104, 158, 210, 240 K; ii) under bias excitation, two types of spectra
have been obtained with peaks around 160, 240K (type I) and 182, 280 K (type II), respectively. The activation energies have
been estimated to be 0.38 eV for the peak showing up at 182 K, and 1.05 eV for the one at 280 K. |
