(a) Distance ratios of growth fronts along [10]sq and [11]sq directions, (b1)–(b3) three characteristic morphologies and (c1)–(c3) the corresponding atomic configurations of the area enclosed by the white box in panels (b1)–(b3). Black, red, and blue triangle symbols in panel (a) are simulated with parameter n̄ = −0.1, −0.07, and −0.05, and the curves represent the corresponding smoothed data. The color bars in panels (b1)–(b3) mark the variation of the smoothed atomic density field nsmooth.
