摘要

实验首次测定了温度为 77-300 K 的 InAs/GaSb 超晶格的复折射率随频率的变化，在这种超晶格中，塑性松弛受到界面应变补偿的抑制，基本吸收边在远红外范围内。

One-Electron Spectrum of a Short-Period InAs/GaSb Superlattice with Interface Compensation of Strains

The frequency dependence of the complex refractive index of an InAs/GaSb superlattice where plastic relaxation is suppressed by interface compensation of strains and the fundamental absorption edge falls in the far-infrared range is experimentally determined for the first time at temperatures of 77–300 K. The energy structure of the superlattice minibands and its variation with temperature are discussed.
