Zhang and published by . This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the k-conservation restriction the intrinsic luminescence from the two-dimensional electron gas (2DEG) in modulation-doped (MD) quantum wells (QWs) of high structural perfection consists of a sharp peak centered around the band gap instead of a step-like emission band extending up to the Fermi edge as expected. Therefore, in such QWs it is not possible to study the density of states as well as the optical processes involving electrons near the Fermi edge directly by means of photoluminescence (PL) experiments. In order to observe the luminescence involving all occupied electron states below the Fermi edge in the 2DEG, some mechanism has to be introduced to localize photogenerated holes and relax the k-conserving law. Alloy fluctuations may localize the holes in ternary MD QW, but the random character of this localization potential causes some difficulty for reproducible studies.

Book Synopsis Optical Properties of Semiconductor Nanostructures by : Marcin L. Sadowski
Download or read book Optical Properties of Semiconductor Nanostructures written by Marcin L. Sadowski and published by Springer Science & Business Media. This book was released on 2000-06-30 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical methods for investigating semiconductors and the theoretical description of optical processes have always been an important part of semiconductor physics. Only the emphasis placed on different materials changes with time. Here, a large number of papers are devoted to quantum dots, presenting the theory, spectroscopic investigation and methods of producing such structures. Another major part of the book reflects the growing interest in diluted semiconductors and II-IV nanosystems in general. There are also discussions of the fascinating field of photonic crystals. `Classical' low dimensional systems, such as GsAs/GaAlAs quantum wells and heterostructures, still make up a significant part of the results presented, and they also serve as model systems for new phenomena. New materials are being sought, and new experimental techniques are coming on stream, in particular the combination of different spectroscopic modalities.

Download or read book Electrons, Phonons and Their Interactions in Novel Modulation Doped GaAs/AlAs Based Quantum Wells written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lowest energy interband transitions in AlGaAs/AlAs quantum wells involve electrons localized in the AlAs x-valleys and holes confined in the AlGaAs layers. These transitions are indirect in both real as well as in kappa-space and are accompanied by strong replicas of the GaAs and AlAs phonons. When a magnetic field is applied perpendicular to the layers a large reduction in the recombination intensity is observed. This reduction is attributed to magnetic field induced localization of the carriers which results in a reduction of the electron-hole wavefunction overlap. We have also studied photoluminescence spectra from type-II, n-type, modulation doped GaAs/AlAs quantum wells due to radiative recombination of electrons localized in the AlAs x-valleys with holes confined in the GaAs layers. In the presence of a magnetic field the emission spectra exhibit features associated with transitions among the AlAs x-valley Landau levels and photo-injected holes. The slopes of these transitions yield an effective mass m = 0.44 for the electrons.

Book Synopsis Quantum Anomalous Hall Effect in Hg_1-yMn_yTe Quantum Wells by :
Download or read book Quantum Anomalous Hall Effect in Hg_1-yMn_yTe Quantum Wells written by and published by . This book was released on 2010 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantum Hall effect is usually observed when the two-dimensional electron gas is subjected to an external magnetic field, so that their quantum states form Landau levels. In this work we predict that a new phenomenon, the quantum anomalous Hall effect, can be realized in Hg{sub 1-y}Mn{sub y}Te quantum wells, without the external magnetic field and the associated Landau levels. This effect arises purely from the spin polarization of the Mn atoms, and the quantized Hall conductance is predicted for a range of quantum well thickness and the concentration of the Mn atoms. This effect enables dissipationless charge current in spintronics devices.
