  • Understanding solute effect on grain boundary strength based . . .
    The large atomic radius of p-block solutes and the polar electronic interaction between them and Cu will cause an embrittlement effect on grain boundary, which explains the experimental
  • Understanding Grain Boundary Electrical Resistivity in Cu . . .
    Grain boundaries (GBs) in metals usually increase electrical resistivity due to their distinct atomic arrangement compared to the grain interior While the GB structure has a crucial influence on the electrical properties, its relationship with resistivity is poorly understood
  • Grain Boundaries: Breakthrough Findings in Materials Research
    Grain boundaries can be broadly classified into ordered and disordered configurations Low-energy boundaries, such as certain CSL boundaries, align in repeating patterns that enhance stability These ordered grain boundaries exhibit well-defined atomic columns, as seen in Σ3 twin boundaries
  • Atomic unveiling of segregation-induced grain boundary . . .
    Grain boundary (GB) structural transition extensively exists in various materials and has significant influences on material properties However, the atomic investigation of GB structural transition and how this transition acts on GB properties such as stability and migration remain elusive
  • Understanding grain boundary electrical resistivity in Cu . . .
    atomic structure of the GB compared to the grain interior This creates a fluctuation in the periodic atomic potential from the adjacent crystals across the boundary, leading to electron scattering at the boundary by a potential wall The magnitude of the potential wall is associated with the GB structure and its chemical bonding
  • Effects of Grain Boundaries and Surfaces on Electronic and . . .
    Structure-property relationships between extended defects, such as surfaces and grain boundaries of solid electrolytes, and their mechanical and electronic properties are established Twinning-type grain boundaries show low excess energy, indicating that they are representative of grain boundaries in polycrystalline SE materials
  • Understanding Grain Boundary Electrical Resistivity in Cu . . .
    Grain boundaries (GBs) in metals usually increase electrical resistivity due to their distinct atomic arrangement compared to the grain interior While the GB structure has a crucial influence on the electrical properties, its relationship with resistivity is poorly understood Here, we perform a systematic study on the resistivity–structure relationship in Cu tilt GBs, employing high
