Pyrolysis properties of metallo-organic precursors, di- isopropyltelluride (DIPTe) and dimethylcadmium (DMCd), in a MOCVD reactor have been investigated by in-situ mass spectroscopy. In particular, possible gas phase reactions as well as pyrolysis mechanism are analysed. Interaction between the two precursors and its influence on pyrolysis temperature are explored under the CdTe, CdTe growth conditions.
