The simplest form of rhombohedral silicon carbide is unknown. Previous studies of the elusive 9R-SiC have failed to show whether this polytype is stable as a bulk material. Here, we demonstrate that when molecular bonds along the c-axis of 2H-SiC are broken under tension, miniscule levels of stackin...
