Notes:
We have studied the impact of the chemical nature of additional gases fed into themodified physical vapor transport (M-PVT) growth cell. In particular experiments were carried outusing helium, argon, nitrogen and propane in the growth setup. Numerical modeling was used toaddress the underlying physical and chemical effects that impact the global temperature field. It isfound that chemical decomposition of complex gases plays a secondary role as heat source or sink.However, temperature variations related to varying gas compositions fed to the systems areprimarily induced by changes of the graphite foam isolation properties
