Control of the Supersaturation in the CF−PVT Process for

In the classical sublimation growth of silicon carbide (SiC) single crystals, the supersaturation in the surrounding of the seed is mainly controlled by pressure and temperature distributions within the growth cavity. Precise control of the supersaturation is difficult, especially if it needs to be adjusted during the process. In the first part of the paper, an experimental study performed in
