摘要

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.
