单层二硫化钼（MoS2）的光吸收特性研究因其在可见光光电和光子器件中的应用而受到广泛关注。本文设计了一种含MoS2单层的一维光子晶体，以提高其光吸收。采用传输矩阵法（TMM）计算了不同设计下TE模和TM模的反射谱和吸收谱。我们发现所设计的结构的光吸收波长可以通过改变1DPC的周期数或使用不同的材料来调节。(C)2016爱思唯尔B.V.保留所有权利。
Investigation of optical absorption of monolayer Molybdenum disulfide, MoS2, has attracted intense attention for its application in the visible optoelectronic and photonic elements. In this paper, one-dimensional photonic crystals (1DPCs) including MoS2 monolayer are designed toward increasing the optical absorption. Reflection and absorption spectra for TE and TM modes are calculated by transfer matrix method (TMM) for different designs. We found that the optical absorption wavelength of designed structures can be tuned by changing the number of period or using of different materials in the 1DPC. (C) 2016 Elsevier B.V.
