Superconductivity in twisted bismuth bilayers
Isaías Rodríguez, Renela María Valladares, David Hinojosa-Romero +2
First-principles calculations for two twisted bismuth bilayers, each with 120 atoms, were studied by means of the electronic density of states and vibrational density of states. Me…
Could Negative Pressures Turn Bismuth into a Metal? The Case of the Expanded
Flor B. Quiroga, David Hinojosa-Romero, Alexander Valladares +3
Materials may behave in non-expected ways when subject to unexpected conditions. For example, when Bi was turned into an amorphous phase (\textit{a}-Bi) unexpectedly it became a su…
Superconductivity versus magnetism in the palladium 'ides': Pd(H/D/T)
Isaías Rodríguez, Renela M. Valladares, Alexander Valladares +2
In general, conventional superconductivity and magnetism are competing phenomena. In some alloys this competition is a function of the concentration of the elements. Here we show t…
Possible superconductivity in Bismuth (111) bilayers. Its electronic and vibrational properties from first principles
David Hinojosa-Romero, Isaías Rodríguez, Alexander Valladares +2
Using a 72-atom supercell we report ab initio calculations of the electronic and vibrational densities of states for the bismuth (111) bilayers (bismuthene) with periodic boundary…
