Summary: Pd3P2S8 is a semiconductor containing Kagome lattices with various physical phenomena. Structural searches revealed four phases, two in the P3?m1 space group (P3?m1 -1 and P3?m1 -2) and two in the C2/m space group (C2/m -1 and C2/m -2), with all but C2/m -2 phase being dynamically stable. Electron-phonon calculations confirmed that both phases exhibit superconductivity, with the P3?m1 -1 phase undergoing a semiconductor-to-superconductor transition and achieving a maximum Tc of 9.13 K at 70 GPa. This study expands the options for studying superconductivity in materials with Kagome lattices.

Summary: We performed first-principles Eliashberg calculations for several conventional superconductors, investigating the importance of self-consistency in the calculation. By comparing the self-consistent results with the one-shot calculation results for the self-energy of electrons, we found that the difference between them becomes larger for systems with rapidly changing density of states around the Fermi level, such as those with van Hove singularities in pressurized hydrides.

Summary: From first-principles density functional theory calculations, we propose hexagonal layered MgB3C3 as a potential phonon-mediated superconductor at 59 K, which is far higher than the superconductivity of MgB2 (approximate to 39 K). The MgB3C3 is energetically and dynamically stable at ambient pressure in the P-62m hexagonal structure with c/a approximate to 0.79 and forms in stacks of honeycomb B-C layers with Mg as a space filler. Band structure calculations indicate that the bands at the Fermi level derive mainly from B and C orbitals in which two sigma and two pi bands both contribute to the total density of state. The pi bands are found to be strongly coupled with out-of-plane acoustic phonon mode, while the sigma bands coupled with the in-plane bond-stretching optical E' phonon modes produces a sizable superconductivity in MgB3C3.

Summary: This study demonstrates using density functional perturbation theory that aluminum exhibits the largest change in thermal conductivity under extreme pressures at room temperature compared to any other known material. This is attributed to the relatively larger increase in mean free paths and lifetimes of electrons in aluminum under higher pressures due to weaker electron-phonon coupling.

Summary: In this study, CaO-Al2O3-CaF2 slags were calculated using first-principles molecular dynamics to guide the development of CaO-Al2O3-based non-reactive mold flux for low-density high-strength steel production. The results showed that the stability order of the corresponding bonds was Al-O > Ca-F > Ca-O > Al-F. The addition of F- enhanced the stability of Al-O and Al-F bonds, decreased the stability of Ca-O bonds, and had almost no effect on Ca-F bonds. Furthermore, the addition of F- reduced the viscosity of the slags, especially for slags with lower CaO/Al2O3 ratio. Al-O and Al-F bonds were charge-transfer bonds, while Ca-O and Ca-F bonds were ionic bonds. The unstable hexahedron AlO4F dynamically evolved into tetrahedral AlO3F and AlO4.

Summary: C-60-based molecular solids have potential applications in electrode materials and solid state electrolytes in alkali ion batteries. Using density functional theory (DFT), the diffusion of lithium and sodium ions in the C-60 lattice was studied. The diffusion mechanism involved motion between tetrahedral and octahedral voids within the lattice. The activation barriers for ion diffusion were determined to be 0.34 eV for lithium and 0.28 eV for sodium, which are competitive with current solid state electrolytes and electrode materials. These findings provide insights into the diffusion mechanisms of alkali ions in C-60 lattices and suggest the potential use of C-60 as important components in alkali-ion batteries.

Summary: The recent discovery of nickel oxide superconductors highlights the importance of first-principles simulations in understanding the formation of bound electrons in superconductivity. However, density functional theory (DFT) cannot properly account for the strong electronic correlation effects in oxides, disqualifying this technique. Sr1-xKxBiO3 superconductors, being isostructural to nickel oxides, provide an ideal platform for studying complex superconductors and the underlying pairing mechanism. This study shows that parameter-free DFT simulations can accurately capture the experimental features and quantities of Sr1-xKxBiO3 superconductors, including the prediction of a phase transition and the electron-phonon coupling constant in agreement with experiments.

Summary: Solder void defects have negative impacts on the reliability of die packages, leading to strict requirements for solder void size control. A study on the vacuum reflow process using Pb95Sn5 solder showed that critical conditions such as higher reflow temperature, faster pressure pump-down rate, and longer vacuum dwell time above threshold levels can effectively reduce solder void size. Applying threshold conditions in a large volume reflow oven with industrial settings can achieve solder void sizes well below industry criteria.

Summary: In this study, the electrical and optical response of a multilayer thin film composed of lossless and lossy materials in an alternating arrangement under a transverse voltage is simulated using a polynomial approach. The model treats the multilayer thin film as an effective capacitor constructed from coupled capacitors, with the interface between layers representing the coupling. By adjusting the transverse electric potential, the model can predict nontrivial optical responses.

Summary: Al0.85Ga0.15As0.56Sb0.44 has been found to be a material of interest for 1550 nm low-noise SWIR avalanche photodiodes. New experimental data shows lower noise at higher multiplication values than previously reported. The discrepancies with classical theory suggest that the impact ionization probability distributions for electrons and holes in this material may follow a Weibull-Frechet distribution function even at low electric fields.

Summary: In recent years, the power electronics packaging industry has tightened the criteria for acceptable solder void size to below 5% in power packages. Vacuum reflow technology has been introduced to reduce solder void size in applications with large contact area and low bond line thickness (BLT). The pressure level is the most significant factor, followed by the pressure pump-down rate, while the vacuum dwell time has minimal effects. The critical pressure level threshold for achieving 100% yield in meeting the 5% criteria is estimated to be 8 kPa. Effective solder void size reduction has been consistently demonstrated for various solder alloys by using nonclean and low residue flux in post reflow as part of solder paste selection.

Summary: The thickness of semiconductor die is decreasing due to improved power efficiency in electronic packages. Ultrathin die with convex warpage can cause solder void removal issues during solder reflow, leading to packaging reliability problems. Die-pop phenomenon is observed during the pressure-profile reflow process for ultrathin dies. However, the application of the two-step pressure-profile and medium reflow temperature profile in vacuum reflow process has successfully eliminated die-pop occurrence. Combining with appropriate selection of solder paste volume and bond line thickness, most samples achieved solder void size below 2% of die size with zero die pop detected, without compromising manufacturing productivity.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
