At the nano and atomic scales, the interplay between a material's structure and its interaction with electric, thermal, and mechanical fields can induce pronounced electron field emission effects. These effects, in turn, can trigger dynamic, cascading phase transitions within the material's microstructure, leading to thermal runaway phenomena that span both spatial and temporal dimensions. Understanding this complex phenomenon is paramount for elucidating the fundamental mechanisms underlying vacuum electrical breakdown at the microscale. Such insights hold significant promise for optimizing the performance of micro-nano electron field emission devices, as well as enhancing the energy injection efficiency and stability of compact high-energy linear particle accelerators. For an extended period, cutting-edge numerical computation theories and core simulation software in this domain have been dominated by European and American research institutions, exemplified by CERN. Consequently, related computational tools have remained largely proprietary, with limited open-source availability, sharing, or commercialization.
