The circular photogalvanic effect and the circular photon drag effect are observed and investigated in detail in (110)-grown quantum well structures. The experimental data are well described by phenomenological theory and microscopic models of both e

We present a T-shaped waveguide for a quantum-wire intersubband laser in the GaAs/AlGaAs heterosystem for the midinfrared spectral region around 8 mm. Such a device is fabricated using the Cleaved Edge Overgrowth (CEO) technique. The suggested wavegu

Employing the Cleaved Edge Overgrowth technique, GaAs/AlGaAs quantum wire cascade structures have been fabricated. The quantum wire states are formed by the perpendicular overlap of two confinement potentials, one resulting from a strong potential mo

An experiment to probe spin-polarized currents in the quantum Hall regime is suggested that takes advantage of the large Zeeman-splitting in the paramagnetic diluted magnetic semiconductor zinc manganese selenide (Zn$_{1-x}$Mn$_x$Se). In the proposed

A novel mid infrared emitting GaAs/AlGaAs quantum wire cascade device is presented that is fabricated using the cleaved edge overgrowth technique. The samples are pumped electrically. Radiative electronic transitions between discrete energy levels in

We present a quantum-cascade emitter in the galliumarsenide/aluminum–galliumarsenide (GaAs/AlGaAs) heterosystem whose emission properties are controlled by an additional electric field perpendicular to the transport direction. In our case, the addi

We discuss the influence of current-induced heating on the current-voltage (I-V) characteristics and the spectral behavior in quantum well and quantum wire intersubband emitter structures. A conventional quantum cascade laser structure in the AlGaAs/
