Ambient-pressure high-temperature superconductivity in stoichiometric hydrogen-free covalent compound BSiC2

High superconducting critical temperature ( ${T}_{c}$ ) of 73.6 K at ambient pressure is predicted in BSiC _2 by means of the first-principles electron–phonon calculations. Without the need for doping or pressurization, the stoichiometric BSiC _2 exhibits strong electron–phonon coupling (EPC) and hi...
