Insights into the CVD process of heavier group 13 nitrides with intramolecularly coordinated single-source precursors

  • The following thesis deals with the elucidation of the gas-phase decomposition mechanism of the intramolecularly coordinated Single-Source Precursors \([Me_{2}N(CH_{2})_{3}]_{2}MN_{3}\) using Matrix-isolation FTIR spectroscopy. Single-Source Precursors are known to be suitable compounds for the MOCVD growth of MN thin films or nanostructured materials (nanorods, nanowiskers) which are particularly interesting, mainly because of their potential use for the manufacture of optoelectronic devices operating in the blue green spectral region. Thus, the aim of the work was to understand and subsequently control their decomposition behaviour on a molecular level. The first part of the thesis focuses on a series of high-vacuum pyrolysis studies of intramolecularly coordinated halides \([Me_{2}N(CH_{2})_{3}]_{2}\)MX which serve as model compounds for the azides, the actual relevant SSPs. The decomposition of the SSPs is examined in the second part and folowingly the pyrolysis mechanisms are discussed.
