摘要

实验研究了通过斜角沉积获得的基于钴纳米螺旋阵列的手性薄膜结构。实验表明，在旋转倾斜基底上进行电子束蒸发的条件下，会形成沿同一方向缠绕的纳米螺旋阵列。通过改变基片的旋转速度，可以改变这些螺旋的几何尺寸（螺旋间距、螺旋半径）。由此获得的手性元表面在反射左右圆偏振光时具有明显的非对称光学特性。

Chiral Thin Film Structures Based on Arrays of Cobalt Nanohelices Obtained By Oblique Deposition

Chiral thin film structures based on arrays of cobalt nanohelices obtained by oblique angle deposition were experimentally studied. It was shown that, in the conditions of electron-beam evaporation on rotating inclined substrate, arrays of nanohelices wound in the same direction are formed. By varying substrate rotation speed, it is possible to change geometrical sizes of those helixes (helix pitch, helix radius). The thus obtained chiral metasurface demonstrates pronounced asymmetry of optical characteristics at the reflection of right and left circular polarized light.
