Jb, Jc and their estimate of the ring exchange interaction K4=80tb2tc2/(U−(V1+V2+V3)/3)3 giving K4/Ja ~ 0.11 indicate that the EtMe3Sb[Pd(dmit)2]2 is located near the border of the antiferromagnetic phase but in the QSL side, consistently with our full quantum ...

(v F ) near the Fermi vF = 2EF m Then use this value to estimate the conductivity (σ) as: (6) ne2τ ne2l l σ = = ,τ = m mvF vF (7) where τ , m, n, e, and l are the time between two collisions, mass of electron, number of electrons, electron's charge...
Machine learning a defect’s effect A method for quickly predicting the dominant equilibrium atomic-level defects in a material is developed by researchers in the USA. Crystalline materials derive many of their attributes from the regular and symmetric arrangement of their atoms. Consequently, a missi...

The band structure of MoS2 has been previously explored, including the effect of interlayer pressure [25]. Here, we studied the changes produced in the optical properties of MoS2 when adsorbing Pt. The present work consists of two stages: First we performed static calculations on four cases of...
Moreover, a charge depletion around the Si atom and near the bond edge of the C atom can be observed, as well as a more minor charge depletion and accumulation on the C-C bond edges close to the Si-C bond. Figure 10. Isosurface of differential charge density of (a) Cl-SiNW-C8H...
Once interactions between Li ions are taken into consideration, due to its sensitive dependence of near atom environment, the Li+ migration energy barrier might change at any time in Li+'s migration process. Thus, it is hard to get the energy barriers momentarily. However, Li+ migration ...

The simulations were carried out in a cubic box with a side length of 15.6406 Å. Figure 5. Autodissociation of H2O (top): Average force acting on the constraint. (bottom): Free energy obtained by integrating the average forces. Note the drop in free energy at 1.5 Å is caused by...
