- W2057153968 abstract "Low-field drift mobility for transport parallel to the interfaces in a polar semiconductor quantum well is calculated following an iterative procedure. Calculations are carried out in the size-quantum-limit approximation for a degenerate electron gas. Screening of the electron–phonon interaction via acoustic deformation potential, piezoelectric of the accoustic branch, and longitudinal optical mode couplings is taken into account by means of a dielectric function deduced in an earlier work. Confinement of LO vibrations is also taken into account by means of an appropriate Hamiltonian successfully employed in previous works. The role of the electron–LO-phonon interaction is accurately established and the conclusion is drawn that this coupling becomes considerable at intermediate and very important at sufficiently high temperatures for quantum wells of the GaAs/AlGaAs type. Comparison with experiment gives an acceptable agreement between calculated and measured mobility values. Mit einem Iterationsverfahren wird die Niedrigfeld-Driftbeweglichkeit für den Transport parallel zu den Grenzflächen eines polaren Halbleiter-Quanten-Wells berechnet, und zwar in der Näherung des Size-Quantenlimits für ein entartetes Elektronengas. Die Abschirmung der Elektron–Phonon-Wechselwirkung mittels Kopplung durch das akustische Deformationspotential, die akustisch-piezoelektrischen und die longitudinal-optischen Moden wird durch eine in einer früheren Arbeit abgeleitete dielektrische Funktion berücksichtigt. Confinement der LO-Schwingungen wird ebenfalls durch einen in einer früheren Arbeit verwendeten, geeigneten Hamilton-Operator einbezogen. Die Rolle der Elektron–LO-Phonon-Wechselwirkung wird exakt nachgewiesen, und es wird gefunden, daß diese Kopplung für QW vom Typ GaAs/AlGaAs bei mittleren Temperaturen beträchtlich und bei hinreichend hohen Temperaturen sehr bedeutend ist. Vergleich mit dem Experiment ergibt eine annehmbare Übereinstimmung zwischen theoretischen und gemessenen Beweglichkeitswerten." @default.
