(ZnSe)_n/(ZnS)_m应变层超晶格的光吸收系数

Optical Absorption Coefficient in (ZnSe)_n/ (ZnS)_m Strained-lay Superlattices

用L-K有效质量理论研究［001］方向生长的（Znse）n／（ZnS）m应变层超晶格的电子结构和光吸收系数．结果表明，光吸收系数与附宽和垒厚有关．

The subband structures and optical absorption coefficient of (ZnSe)_n/(ZnS)_m strained-lay superlattices in [001] were calculated with the effective-mass approximation. The results indicate that the optical obsorption coefficient varies with the well-width and the barrier-width.
