Stabilizing a hydrogen-rich superconductor at 1 GPa by charge transfer modulated virtual high-pressure effect
Stabilizing a hydrogen-rich superconductor at 1 GPa by charge transfer modulated virtual high-pressure effect
Applying pressure around megabar is indispensable in the synthesis of high-temperature superconducting hydrides, such as SH$_3$ and LaH$_{10}$. Stabilizing the high-pressure phase of hydride around ambient condition is a severe challenge. Based on the density-functional theory calculations, we give the first example that the structure of hydride CaBH$_5$ predicted above …
