Thermodynamic Assessment of the Gallium-Nitrogen System
نویسنده
چکیده
Thermochemical and phase diagram data for the Ga–N system were assessed by employing the CALPHADmethod. A consistent model representation of available thermodynamic properties agrees well with the critically evaluated experimental data. Thermodynamic extrapolation/interpolation of these data was applied to estimate the sublimation andmelting characteristics of theGaN compound: at atmospheric pressure of nitrogen, gallium nitride sublimates incongruently by decomposing into nitrogen-rich gas and gallium-rich liquid, but can melt congruently at high nitrogen pressure ( 4.9 GPa).
