中文摘要：

理论上采用转移矩阵法研究了具有P3OT/AlN多层膜结构的一维半导体-有机物型光子晶体的光学特性.计算结果表明：由厚度分别为30,30nm的P3OT,AlN薄膜组成的多层膜结构,在中心波段为275nm处有一不完全的光子带隙存在,反射率最高可达98%;而且可以通过调整薄膜厚度、填充比等参数对光子带隙的位置、反射强度进行调制.因此,这种一维半导体-有机物型光子晶体对在紫外波段获得具有一定功能的光子晶体具有重要的指导意义.

英文摘要：

Theoretical calculations via the transfer matrix method （TMM） are performed to investigate optical properties of one-dimensional semiconductor-organic photonic crystals （SOPC） with periodic conjugated polymer （3-octylthiophenes,P3OT）/AIN multilayer structure. The SOPC presents incomplete photonic band gap behavior in the UV region. P3OT/A1N multilayers with two pairs of 30nm-P3OT and 30nm-A1N layers exhibit a photonic band gap at a central wave- length of about 275nm,and the highest reflectivity reaches 98%. Furthermore,the band gaps are confirmed to be tunable by adjusting the lattice period and the filling fraction. As a consequence, the SOPC is important for achieving materials with an incomplete band gap in the UV region.
