An experimental study of the direct-gap related optical transitions in strain-compensated Ge/Si 0.15 Ge 0.85 multiple quantum wells (MQWs) is presented. These structures are of particular interest due to the proximity of G-type and L-type conduction band states and due to their type I band alignment
