Lattice Energy: The lattice energy of a compound is defined as the formation of gaseous ions from a solid ionic compound. It depends on the charge present on the ions and the size of the ions. Smaller the size and higher is the charge on ions, larger is the ...

Lattice Energy: Lattice energy is a term used for how strong the ions are attracted to each other within an ionic compound. The greater the distance between ions, the lesser is the lattice energy value because there are weaker forces of attraction...
The energy per unit cell of the SCQMM structure lying along the x–direction, when coupled to an EM vector potential A = Az (x, t)zˆ, can be readily written as17,18 H = ∑{[ϕ n2 − 2 cosϕn] + [α n2 + β2 (αn+1 − αn)2] + [2 cosϕn(1 ...
Our total energy and formation enthalpy results show that [Formula: see text] undergoes a phase transition from the orthorhombic Pnma phase to the polar R3c one at a lithium concentration of x=0.7. Under pressure the system in the R3c structure exhibits a phase transition to the Pnma one ...
We have investigated the structural and lattice dynamical properties of XB 2(X=Sc,V,Ti) by using first-principles total energy calculations. Specifically, the lattice parameters (a, c) of the stable phase, the bond lengths of X–B and B–B atoms, phonon dispersion curves and the correspondi...
Since then concentrated effort have been put forward to simulate AHE without the presence of a magnetic field.The key point of such proposals is to engineer nontrivial topology of energy bands where the Hall conductance is related to the integral of the Berry curvature of the filled part of ...
