Fig. 2: Relative enthalpies (ΔH) and crystal structures of the considered XC2H8 compounds.

From: Prediction of p-block-based ternary superconductors XC2H8 at low pressure

Fig. 2

Relative enthalpies of a GaC2H8, b InC2H8, c TlC2H8, d SnC2H8, e PbC2H8, f SbC2H8, g BiC2H8, h TeC2H8, and i PoC2H8, with respect to the \(Fm{\bar{3}}m\) structure from 0 to 100 GPa. The following crystal structures were considered: \(Fm{\bar{3}}m\), P42nm, \(P{\bar{4}}\), Fd3m, I41/amd, I4/mmm. The arrows point to the pressures where the \(Fm{\bar{3}}m\) ternaries are predicted to be energetically stable.
