- Abstract
Using structure prediction software based on particle swarm optimization algorithm, we have discovered a new atmospheric superconductor BeB2C, and the electron–phonon Wannier (EPW) software was used to calculate the superconducting critical temperature, the obtained Tc = 30.3 K, when the effective Coulomb shielding constant and the Ep-ph constant are set to 0.16 and 0.8036 respectively. At the same time, first-principles calculation method was used to study the energy bands and density of states of the material.
