Abstract
We report a combined reflectance difference spectroscopy and scanning tunneling microscopy study of ultrathin α-sexithiophene (6T) films deposited on the Cu(110)-(2×1)O surface. The correlation between the layer resolved crystalline structure and the corresponding optical spectra data reveals a highly sensitive dependence of the excitonic optical properties on the layer thickness and crystalline structure of the 6T film.
摘要
我们报告了一项关于超薄α-六噻吩（6T）薄膜在 Cu(110)-(2×1)O 表面上的反射差光谱和扫描隧道显微镜研究。层分辨晶体结构与相应的光谱数据之间的相关性揭示了 6T 薄膜的层厚度和晶体结构对激子光学性质的高度敏感依赖性。
