Summary
- What is new: The new finding is the identification of specific transformations in Li$_x$BC morphologies that could lead to the creation of metastable superconductors with critical temperatures up to 73 K, a significant advancement in the field of conventional superconductivity.
- Why this is important: Previous attempts to induce superconductivity in LiBC by delithiation failed to achieve the expected transition to superconducting states.
- What the research proposes: The research proposes the reintercalation of Li$_x$BC with select alkali and alkaline earth metals to create new, potentially synthesizable metastable superconductors.
- Results: Newly predicted NaBC and Li$_{1/2}$Na$_y$BC phases are likely true ground states at low temperatures, suggesting a rich compositional space for developing high $T_{c}$ superconductors in ambient-pressure conditions.
