| Resumo | A self-consistent set of thermochemical data for 88 chemical species in the B/F/H/N system are obtained from ab initio electronic structure calculation. Calculations were performed for both stable and radical species. The quantities calculated include the atomization energy (SD0), heat of formation (DHf) at 0K and 298.15K and bond dissociation energies (BDE) for all species. In this work we will present the NxHyFz species, in a total of 16 species, where only 4 species have experimental or theoretical reference data to be compared. First of all the well know species in the NxFy and NxHy system are analyzed, in a total of 12 species, for which the calculation methodology is tested by comparing the calculated properties with the experimental results. Then we determined the properties for the 16 desired species in the NxHyFz system. Good agreement is found between the calculated data and experimental or theoretical reference data for the quantities analyzed in this work. The error between the calculated thermodynamic properties and the experimental or theoretical reference data for the species analyzed here are compared with the error bar. Polynomial fits of the predicted thermodynamic data (heat capacity, entropy and enthalpy) over the 200-6000K temperature range are also included. The species analyzed here are important in a kinetic mechanism in the growth of boron nitride films in a CVD reactor. It is generally difficult to optimize conditions in a CVD reactor because films properties depend on complex interactions involving heat and mass transport, chemical kinetics, and thermochemistry. Developing a reliable set of thermodynamic data is a necessary first step for system optimization, since it provides important constraints on the possible reaction mechanism. |
