Tunable intersubband transitions in ZnO/ZnMgO multiple quantum wells in the mid infrared spectral range

We report on controllable tuning of intersubband transitions in ZnO/Zn0.60Mg0.40O multiple quantum well structures grown by molecular beam epitaxy on sapphire. The transitions from the first to the second electronic energy state within the conduction band are directly observed by infrared spectrosco...
