The effect of pressure on the structural properties of lanthanum sesquicarbide La2C3 (T_c = 13 K) has been investigated at room temperature by angle-dispersive powder x-ray diffraction in a diamond anvil cell. The compound remains in the cubic Pu2C3-type structure at pressures up to at least 30 GPa. The corresponding equation of state parameters are reported and discussed in terms of phase stability of La2C3. Pressure-volume data of the impurity phase LaC2 are reported also for pressures up to… Expand
Structural transformation and vibrational properties of BaO2 at high pressures
The tetragonal ambient-pressure phase of BaO2 CaC2-type, space group I4/mmm with sixfold coordination of Ba atoms and O2 dumbbells was found to transform reversibly to an orthorhombic modificationExpand
Carbon Based Superconductors
We review the characteristics of some carbon based novel superconductors which emerged in the past two decades since the discovery of superconductivity in the high-T c oxocuprates. In particular, weExpand
Structural behavior of the acetylide carbides Li2C2 and CaC2 at high pressure.
The effects of high pressure (up to 30 GPa) on the structural properties of lithium and calcium carbide, Li(2)C( 2) and CaC(2), were studied at room temperature by Raman spectroscopy in a diamond anvil cell to suggest an irreversible amorphization of the acetylide carbides. Expand
Structure and Phase Stability of CaC2 Polymorphs, Li2C2 and Lithium Intercalated Graphite : A Revisit with High Pressure Experiments and Metal Hydride–Graphite Reactions
Alkali (A) and alkaline earth (AE) metals can form carbides and intercalated graphites with carbon. The carbides mostly represent acetylides which are salt-like compounds composed of C22− dumbbell ...
A comparative ab initio study of superconductivity in the body centered tetragonal YC2 and LaC2
Ab initio studies of the electronic band structure and phonon dispersion relations, using the planewave pseudopotential method and the density functional theory, have been made for theExpand
Catenation of carbon in LaC2 predicted under high pressure.
The presented results indicate that catenation of carbon can be realized even in simple inorganic compounds under nonambient conditions. Expand
Pressure stabilization of long-missing bare C6 hexagonal rings in binary sesquicarbides
Carbon (C) is able to form various bonding patterns, including graphene sheets, chains and dimers, but stable bare six-membered C6 hexagonal rings, which are the fundamental structural motifs ofExpand
First-principles study on stability, electronic, and mechanical properties of La–C and Ce–C binary compounds
The phase stability and electronic and mechanical properties of rare earth (RE) carbides (La2C3, LaC2, Ce2C3, CeC2, and CeC) were investigated using first-principles calculations based on densityExpand
Nanoscale fullerene compression of an yttrium carbide cluster.
The results of this study suggest that decreasing the size of a fullerene cage with the same (Y(2)C(2))(4+) cluster results in nanoscale fullerenes compression (NFC) from a nearly linear stretched geometry to a constrained "butterfly" structure. Expand
Superconductivity of Carbides
Carbon-based superconductors can be roughly categorized into two groups. The first includes relatively new superconductors, such as boron-doped diamond, graphite-intercalated compounds (GIC), carbonExpand
