      abstract     = {The cubic diamond (Fd-3m) group IVA element Si has been the
                      material driver of the electronics industry since its
                      inception. We report synthesis of a new cubic (Im-3m) group
                      IVA material, a GeSn solid solution, upon heating Ge and Sn
                      at pressures from 13 to 28 GPa using double-sided diamond
                      anvil laser-heating and large volume press methods. Both
                      methods were coupled with in-situ angle dispersive X-ray
                      diffraction characterization. The new material substantially
                      enriches the seminal group IVA alloy materials landscape by
                      introducing an eightfold coordinated cubic symmetry, which
                      markedly expands on the conventional tetrahedrally
                      coordinated cubic one. This cubic solid solution is formed,
                      despite Ge never adopting the Im-3m symmetry, melting
                      inhibiting subsequent Im-3m formation and reactant Ge and Sn
                      having unlike crystal structures and atomic radii at all
                      these pressures. This is hence achieved without adherence to
                      conventional formation criteria and routes to synthesis.
                      This advance creates fertile avenues for new materials
                      development.},
