Polytype-selective growth of SiC by supersaturation control in solution growth

► We performed polytype-selective growth of 3C-SiC and 6H-SiC by controlling supersaturation. ► The growth rates of 3C-SiC and 6H-SiC had different dependences on supersaturation. ► 3C-SiC grew covering the 6H-SiC seeds completely at a high supersaturation. ► Our kinetics-based polytype control is quite different from conventional technique.
