Collective intersubband transitions in quantum wells: a comparative density-functional study
We use linearized time-dependent (current) density functional theory to study collective transitions between the two lowest subbands in GaAs/AlGaAs quantum wells. We focus on two particular systems, for both of which experimental results are available: a wide single square well, and a narrow asymmetric double quantum well. The aim is to calculate the frequency and linewidth of collective electr...
متن کاملTemperature stability of intersubband transitions in AlN/GaN quantum wells
Temperature dependence of intersubband transitions in AlN/GaN multiple quantum wells grown with molecular beam epitaxy is investigated both by absorption studies at different temperatures and modeling of conduction-band electrons. For the absorption study, the sample is heated in increments up to 400◦C. The self-consistent Schrödinger-Poisson modeling includes temperature effects of the band-ga...
متن کاملCollective Excitations in InAs Quantum Well Intersubband Transitions
Intersubband transitions in semiconductor quantum wells are studied using a density matrix theory that goes beyond the Hartree-Fock approximation by including the full second order electron-electron scattering terms in the polarization equation for the first time. Even though the spectral features remain qualitatively similar to the results obtained with the dephasing rate approximation, signif...
متن کاملStudy of intersubband transitions in Si1-xGex/Si quantum wells using 14-band k⋅p model
Optical intersubband transitions (ISTs) for both in-plane polarization (TE) and normalto-plane polarization (TM) in p-type Si1-xGex/Si multiple quantum wells (MQWs) are investigated using 14-band k⋅p model combined with the envelope-function Fourier expansion method. The results show that the amplitudes of different intersubband transitions for TE and TM polarizations, and the overall absorptio...
متن کاملSuppression of absorption by quantum interference in intersubband transitions of tunnel-coupled double quantum wells
We propose and analyze an efficient scheme for suppressing the absorption of a weak probe field based on intersubband transitions in a four-level asymmetric coupled-quantum well (CQW) driven coherently by a probe laser field and a control laser field. By using the numerical simulation, we find that the magnitude of the transient absorption of the probe field is smaller than the three-level syst...
