Preface
PrefaceSemiconductor quantum structures, such as quantum wells, quantum wires, quantum dots, tunneling barriers, and superlattices, have been the subject of extensive research over the past three decades. Their basic appeal lies in the ability they provide to observe and engineer a wide variety of quantum mechanical effects, both for fundamental studies and for device applications in electronics and photonics. A particularly interesting class of semiconductor quantum devices is based on intersubband transitions, i.e., optical transitions between quantized states within the conduction band (or within the valence bands) in low-dimensional systems. These transitions offer several remarkable features for device applications, including the ability to tailor their center wavelengths, di…
