Effective Bloch equations for strongly driven modulation doped quantum wells

Charge density and plasmon modes in a triangular quantum well model for doped and undoped gated AlGaN/GaN HEMTs... Charge density and plasmon modes in a triangular quantum well

The authors have applied modulation spectroscopy to study intersubband (IS) and interband (IB) transitions in InGaN/AlInN multi quantum well (QW) structures with the QW width

Since the top heavy-hole subband lies above the top light-hole subband, we expect the intensity I, to start at the conduction subband t o the top heavy-hole subband threshold

In a simple picture the spin density fluctuation spectra are proportional to the single particle (= electron hole pair) excitation spectra. In Figure 4 we show the single

The fit of these lines is shown on the right part of fig 2 (continuous lines). The other transitions are found to be recombinations induced by the heavy and light hole coupling..

U. We derive simple analytical expressions for the perpendicular mass, which describes how the confinement energies are influenced, and the parallel mass, which

The phenomenon is understood in terms of a vertical photovoltage induced by the separation of carriers, and is sensed laterally through the in-plane resistances of
