摘要
通过真空镀膜法在单晶硅片上制备了一种新的亚酞菁 (三硝基溴硼亚酞菁 )薄膜。利用全自动椭圆偏振光谱仪研究了该薄膜的椭偏光谱 ,测量了其复折射率、复介电常数和吸收系数 ,估算了薄膜在窗口区域的俘获能级并对其吸收谱的成因作了分析。
A new subphthalocyanine (bromoboron trinitro-subphthalocyanine) thin film was prepared by vacuum deposition on a single-crystal silicon substrate. The ellipsometric spectra of this film have been investigated on an improved rotating analyzer-polarizer (RAP) type of scanning ellipsometer. The optical and dielectric constants, absorption coefficient and trapping levels of this film in the 400 nm-700 nm wavelength region were given. The spectra were explained and discussed as well.
