摘要

我们报道了用化学气相沉积(CVD)制备单层石墨烯的椭偏研究。调查是在一个广泛的光谱范围内进行的，从紫外到近红外，在不同的入射角。与石墨和先前发表的石墨烯数据进行比较，表明这两种材料的光学性质高度相似。

Comparative analysis of optical properties of CVD graphene and graphite via spectroscopic ellipsometry

We report an ellipsometric study of the monolayer graphene prepared by the chemical vapor deposition (CVD). The investigation was carried over a broad spectral range spanning the ultraviolet to the near-infrared at variable incidence angles. Comparison with graphite and previously published graphene data shows a high degree of similarity in the optical properties of these two materials.
