To predict the structures, properties, and chemistry of materials involving silicon oxides; interfaces between these materials; hydrolysis such systems, we have developed ReaxFFSiO, reactive force field. The parameters for this field were obtained from fitting to results quantum chemical (QC) calculations on structures energy barriers a number oxide clusters equations state condensed phases Si SiO2 QC. We expect that ReaxFFSiO will allow accurate dynamical simulations bond breaking processes...
The construction of a predictive model that accurately reflects the spontaneous combustion temperature coal in goaf is fundamental to monitoring and early warning systems for thermodynamic disasters, including gas explosions. In this paper, on basis programming experiment industrial analysis, 381 data sets 9 types are established, feature selection was executed through utilization Pearson correlation coefficient, ultimately identifying O2, CO, CO2, C2H4, C3H8, C3H8/CH4, C2H4/CH4, C2H4/C3H8,...
We derive here the form for exact exchange energy density a that decays with Gaussian-type behavior at long range. This functional is intermediate between B88 and PW91 functionals. Using this modified to match expected Gaussian densities, we propose X3LYP extended functional. find significantly outperforms Becke three parameter Lee–Yang–Parr (B3LYP) describing van der Waals hydrogen bond interactions, while performing slightly better than B3LYP predicting heats of formation, ionization...
Using quantum mechanics (QM, Density Functional Theory) we show that all four phases of barium titanate (BaTiO 3 ) have local Ti distortions toward 〈111〉 (an octahedral face). The stable rhombohedral phase has in (ferroelectric, FE), whereas higher temperature antiferroelectric coupling (AFE) one, two, or three dimensions (orthorhombic, tetragonal, cubic). This FE–AFE model from QM explains such puzzling aspects these systems as the allowed Raman excitation observed for cubic phase, using...
Electron transport and electron-hole balance are the essential processes that determine efficiency luminance of quantum dot light emitting diodes (QLEDs). Those structures with a good capability fast electron charge needed. We developed novel composite layer (ETL) consisting zinc oxide (ZnO) magnesium (ZnMgO) nanoparticles for QLED devices, which can enhance EQE to 13.5%. It is 1.29 times 1.33 compared pure ZnO ZnMgO nanoparticles, respectively. The intensity was increased up 22100 cd/m2 at...
This letter introduces a graphene voltage-adjustable attenuator with an equalization effect.
