An effective strategy of surface & grain boundary co-passivation is demonstrated to access perovskite solar cells with 21.31% champion efficiency as well a highly improved stability less than 3% loss after 2500 hours at humidity 70%.
We report hafnium nitrides under pressure using first-principles evolutionary calculations. Metallic $P{6}_{3}/mmc$-HfN (calculated Vickers hardness 23.8 GPa) is found to be more energetically favorable than NaCl-type HfN at zero and high pressure. Moreover, actually undergoes a phase transition below 670 K ambient ${\mathrm{HfN}}_{10}$, which simultaneously has infinite armchairlike polymeric N chains ${\mathrm{N}}_{2}$ molecules in its crystal structure, discovered stable moderate above 23...
Revved-up rotary: A molecular Wankel motor, the dual-ring structure B(13)(+), is driven by circularly-polarized infrared electromagnetic radiation. Calculations show that this illumination leads to a guided unidirectional rotation of outer ring, which achieved with rotational frequency order 300 GHz.
Abstract Using ab initio evolutionary simulations, we predict the existence of five novel stable Li-N compounds at pressures from 0 to 100 GPa (Li 13 N, Li 5 3 N 2 , LiN and ). Structures these contain isolated atoms, dimers, polyacetylene-like chains rings, respectively. The structure consists atoms 12 icosahedra (with atom in center icosahedron) – such are not described by Wade-Jemmis electron counting rules unique. Electronic is found dramatically depend on composition pressure, making...
High-k dielectric materials are important as gate oxides in microelectronics and potential dielectrics for capacitors. In order to enable computational discovery of novel high-k materials, we propose a fitness model (energy storage density) that includes the constant, bandgap, intrinsic breakdown field. This model, used function conjunction with first-principles calculations global optimization evolutionary algorithm USPEX, efficiently leads practically results. We found number high-fitness...
Heat treatment is one of the most effective controlling factors used to improve thermal conductivity (TC) any alloy castings. In this work, microstructure Al-7Si binary modified by heat at 520 °C for 1−48 h was reported. Both size and shape eutectic Si particles are affected process. Optical microscopy (OM), scanning electron (SEM) X-Ray diffraction (XRD) analysis were carried out characterize phase transformation. The acicular-shaped `Si broken into smaller segments gradually spheroidized....
