Electron momentum density in AlAs
نویسنده
چکیده
A study of electron momentum density distribution in AlAs by means of Compton profiles is presented. The Compton profile measurement on polycrystalline sample of AlAs is performed employing 59.54 keV gamma-rays emanating from Am radioisotope. The measurement is compared with the empirical pseudopotential method (EPM) and there is good agreement between two data. The ionic model calculations for a number of configurations of AlAs (0.0≤x≤3.0) have also been performed while taking free atom profiles and the model suggests transfer of 3.0 electrons from the valence 3s3p state of Al to the 4s4p state of As.

Magnetic Field Induced Spin Polarization of AlAs Two-dimensional Electrons
Two-dimensional (2D) electrons in an in-plane magnetic field become fully spin polarized above a field BP , which we can determine from the in-plane magnetoresistance. We perform such measurements in modulation-doped AlAs electron systems, and find that the field BP increases approximately linearly with 2D electron density. These results imply that the product |g∗|m∗, where g∗ is the effective ...
متن کاملDesign rules for modulation-doped AlAs quantum wells
Thanks to their multi-valley, anisotropic, energy band structure, two-dimensional electron systems (2DESs) in modulation-doped AlAs quantum wells (QWs) provide a unique platform to investigate electron interaction physics and ballistic transport. Indeed, a plethora of phenomena unseen in other 2DESs have been observed over the past decade. However, a foundation for sample design is still lackin...

We report a persistent increase or decrease in the two-dimensional electron density of AlAs or GaAs quantum wells flanked by AlGaAs barriers, brought about by illuminating the samples at T ∼ 4 K while simultaneously applying a voltage bias between a back gate and the two-dimensional electron gas. Control of the final carrier density is achieved by tuning the back gate bias during illumination. ...
متن کاملTuning of the Landé g-factor in AlxGa1−xAs/AlAs single and double quantum wells
We report on the spin dynamics of a high mobility two-dimensional electron gas in a AlxGa1−xAs/AlAs double quantum well structure. For high electron density samples, the gfactor was measured using time-resolved Kerr rotation technique. The g-factor tuning capability was observed by changing the aluminum content x independently in each well. Experiments demonstrated an unusual spin dephasing tim...
متن کاملType II GaAs/AlAs superlattices under high excitation
High intensity photoluminescence data on GaAs/AlAs superlattices and multi quantum wells of type I1 at low temperature are reported. The variation with density of the renormalized band gap reveals the competition between the Hartree energy and the many-body effects (mainly exchange). Preliminary analysis for a lot of samples with widely different periods provides a satisfactory fit with Hartree...
