En route to high Tc superconductivity via Rb substitution of guest metal atoms in SrB3C3 clathrate

Peiyu Zhang, Xue Li, Xin Yang +3

Recently, a host/guest clathrate SrB3C3 with sp3-bonded boron-carbon framework was synthesized at around 50 GPa. On the basis of electron count, the structure is understood as gues…
