摘要

摘要采用非对称连续双沉积的方法制备了由四个相同柱状薄膜组成的等手状雕刻薄膜(ECSTFs)，以显示极化普遍布拉格现象。斜角度光透射测量表明，无论入射平面波的偏振状态如何，总透射率都在20%以下。这些偏振通用带隙可以通过调整入射角来调节。

Polarization-universal bandgaps realized with columnar thin films

Abstract. Equichiral sculptured thin films (ECSTFs) with unit cells comprising a sequence of four identical columnar thin films were fabricated using asymmetric serial bideposition to exhibit the polarization-universal Bragg phenomenon. Oblique-angle optical transmission measurements of the ECSTFs showed bands of total transmittance values under 20%, regardless of the polarization state of the incident plane wave. These polarization-universal bandgaps can be tuned by adjusting the angle of incidence.
