Abstract: | The thermal decompositions of CuInSe2, LiInSe2 and LiInTe2 in vacuum at high temperatures were studied by using TG/DTG coupled with mass spectrometry. For CuInSe2, two steps were found to be significant. Up to 1000 °C Se2 and In2Se evaporate, followed later by Cu2Se. The Li-containing compounds show similar behaviour. However, Li+ was already detected during the first step. Obviously, Li2Se dissociates more readily than Cu2Se. No Cu+ species were detected up to the complete evaporation of CuInSe2. |
