  • Computer simulation to generate 3D atomic structures of twinned SiC.
  • Analysis of surface energy, strain energy, and volume models.

    • Main Results:

    • Periodically twinned beta-SiC nanowires with hexagonal cross-sections (50-300 nm diameter) were synthesized.
    • A zigzag arrangement of uniform-thickness twinned segments was observed along the nanowire length.
    • Computer simulations successfully modeled the 3D atomic structure of the twinned SiC.
    • A linear relationship was found between the thickness of twinned segments and nanowire diameter.

    Conclusions:

    • Minimum surface and strain energy principles explain the formation of periodic twins in SiC nanowires.
    • A constant volume model accurately describes the linear proportionality between twinned segment thickness and nanowire diameter.
    • The findings provide insights into controlling microstructural defects in SiC nanowires for tailored properties.
