    Dynamic Modeling of Stress-Induced Defect Expansion in VCSELs by Yuqi Zhang, Xun Li, Jia Zhao

    Published 2024-01-01
    “…We further exploit a diffusion-limited aggregation (DLA) method in solving the diffusion equation, which describes the random propagation and aggregation of strain in the vicinity of highly strained areas, resulting in defect formation when the stress from accumulated strain surpasses the bonding force of the atoms in the lattice. Our simulation result manages to replicate the dendritic expansion morphology of defects, aligning with experimental observations very well. …”
