倾斜的无图案的，线性偏振照明的电场振荡的平面中的影响增加的方向性特征对齐和减少的离轴顺序在硒-碲沉积物产生的无机向光性生长相对于使用垂直入射。基于光学的生长模拟再现了实验结果，表明形态变化的光子学基础。在生长界面处的光散射的建模显示，照明倾斜增强了散射，该散射使光场沿着偏振平面局部化，并抑制缺陷驱动散射中的协同性。因此，沉积结构的对称性随着照射的不对称性增加而增加，如通过照射入射远离表面法线的倾斜度所测量的。
Inclination of unpatterned, linearly polarized illumination in the plane of the electric field oscillation effected increased directional feature alignment and decreased off-axis order in Se–Te deposits generated by inorganic phototropic growth relative to that produced using normal incidence. Optically based growth simulations reproduced the experimental results indicating a photonic basis for the morphology change. Modeling of the light scattering at the growth interface revealed that illumination inclination enhances scattering that localizes the optical field along the polarization plane and suppresses cooperativity in defect-driven scattering. Thus, the symmetry of the deposited structures increased as the asymmetry of the illumination increased, as measured by the inclination of the illumination incidence away from the surface normal.
