Anisotropic dendritic crystal growth driven by Frank-Read screw dislocation spirals. Terrace step trains circulate outward from core topological singularities, shedding chiral solutal wakes that interlock along low-angle grain boundaries. 螺旋位错台阶流与手性枝晶生长.
台阶流从锚定的柏氏矢量核心被甩出，层层堆叠成灰质的螺面平台。Where adjacent dislocation loops collide, the crystal locks into low-angle tilt boundaries, shedding excess solute into the cold seams between plots.
BCF (Burton-Cabrera-Frank) 台阶生长动力学与四重对称枝晶择优取向的耦合实验。The dislocation cores maintain phase coherence across the center, while the outer step trains undergo Mullins-Sekerka morphological instability. The measured density profile cleanly traces the outward surge (peaking at 0.981 during interlocking) before solutal depletion clears the terrace gaps.
