Webb14 apr. 2024 · In order to obtain accurate results, the cut-off energy was set to 520 eV and the irreducible Brillouin zone grid was used to 5 × 5 × 1 mesh. The energy convergence criterion was 1 × 10 −4 eV as well as −1 × 10 −2 eV for atomic force convergence. In addition, the magnetic moment of the Fe atom was set to 4 μB.

Webb4 maj 2024 · Understanding the atom-sized machine involved both complicated calculations and observations. The team needed to track two thermodynamic quantities known as ergotropy, which is the energy that can be converted to useful work, and entropy, which is related to disorder in the system. Both ergotropy and entropy increase as the … Webb5 apr. 2024 · For SnN 3 O-50, the position of the main peak at ≈1.5 Å is very close to that of SnO 2, which can be attributed to Sn–O/Sn–N coordination, and they are difficult to distinguish in R-space due to the close atomic number of N and O.
