45,50 The most popular EBP procedure is to calculate the band gap centre (BGC),51 which is the average of the VBM and CBM across the Brillouin zone. The primary advantage of calculating the BGC is its insensitivity to the choice of exchange-correlation functional in the DFT framework,51 ...

4c,d). The modulation turns out to be induced by a particular position of the Fermi points in the low-energy band structure: since the YSR band crosses EF at kF ≈ ±π/2d, the Fermi wavelength λF = 2π/kF ≈ 4d is specifically related to the lattice constant. This ...
Using lattice simulations of a one-component $(\lambda \Phi^4)_4$ theory, we have measured the energy spectrum $\omega({\mathbf{k}})$ in the broken phase at various lattice sizes. Our data show that the energy-gap $\omega(0)$ is {\it not} the `Higgs mass' $M_h$ but an inf...
However, various kinds of photoactive semiconductors have been explored (BiVO4, BiNbO4, BiTaO4, WO3 and Fe2O3) possessed VB at +2.86 V, +3.17 V, +3.18 V, +2.8 V, and +2.5 V vs SHE respectively. Due to low band gap and high valance band potential, they became an excellent choice...
It is observed that the crystallite size, energy gap and transparency are decreased; whereas, the dielectric constant, AC conductivity, microhardness and SHG... MS Dileep,KHM Suresh,S Tilak - 《Canadian Journal of Physics》 被引量: 0发表: 2020年 The machining characteristics and surface integrity...
Such a performance gap is mainly attributed to the lack of atomic-level under-standing of Fe-N-C active sites and their ORR mechanism. Besides, unless the cost of expensive electro-catalyst is reduced, the total operation cost of the PEMFC vehicles remains constant. Therefore, developing highly...
Structure Analysis System, the crystallite size, and unit cell volume of MTB-1, MZB-1, and MIB-1 were shown to be larger than the ones of pristine samples (Table S2), which is mainly due to the interstitial incorporation of boron with an ionic radium of 0.3 Å in the lattice19....
(MD) simulations are performed at each of these discreteλstates,λvalues held constant for the duration of the simulation, and the MD trajectories are then postprocessed to calculate the final free energy difference. Though effective, FEP and TI calculations require considerable computational ...
