A large-scale ab initio search for conventional superconductors has revealed new thermodynamically stable and metastable layered metal borocarbides expected to form under ambient pressure display critical temperatures exceeding 70 K.
LiB, a predicted layered compound analogous to the MgB$_2$ superconductor, has been recently synthesized via cold compression and quenched ambient pressure, yet its superconducting properties have not measured. According prior isotropic superconductivity calculations, critical temperature ($T_{\rm{c}}$) was expected be only 10$-$15 K. Using anisotropic Migdal-Eliashberg formalism, we show that $T_{\rm{c}}$ may actually exceed 32 Our analysis of contribution from different electronic states...
First-principles calculations are used to investigate the effect of pressure on lattice stability, electron–phonon properties, and superconductivity in SnSe<sub>2</sub> SnS<sub>2</sub>.
Gold is one of the most inert metals, forming very few compounds, and only a them are currently known to be superconducting. Here we have found yet another chemical compound gold (and silver) that
Electronic structure of ordered alloys CuPd, CuPt, Cu3Pd and Cu3Pt have been studied using Tight Binding Linear Muffin-Tin Orbitals Atomic Sphere Approximation (TB-LMTO-ASA). For the electronic properties, we performed band calculations. Our findings show that all systems considered are metallic in nature. To know contribution orbitals bands, system is analyzed via fat bands which reveal most contributions on valence for from d-orbital conduction s p-orbitals. We also checked magnetic...
Delithiation of the known layered LiBC compound was predicted to induce conventional superconductivity at liquid nitrogen temperatures but extensive experimental work over past two decades has detected no signs expected superconducting transition. Using a combination first-principles stability analysis and anisotropic Migdal-Eliashberg formalism, we have investigated possible Li$_x$BC morphologies established what particular transformations planar honeycomb BC layers are detrimental...
Gold is one of the most inert metals, forming very few compounds, some with rather interesting properties, and only two them currently known to be superconducting under certain conditions (AuTe$_2$ SrAuSi$_3$). Compounds another noble element, Ag, are also relatively rare, superconducting. Finding new materials containing gold (and silver) a challenge - especially having in mind that best high-$T_c$ superconductors at normal based upon their close ''relative'', Cu. Here we report combined...
