Effect of an in-plane magnetic field on microwave photoresistance and Shubnikov-de Haas effect in high-mobility GaAs/AlGaAs quantum wells

چکیده
A recent study of the decay of microwave-induced resistance oscillations (MIRO) in GaAs/AlGaAs quantum wells due to an in-plane magnetic field B‖ has revealed the dominant role of a quadratic-in-B‖ correction to the quantum scattering rate. In the present study, we examine the evolution of Shubnikov-de Haas oscillations (SdHO) with increasing tilt angle in the same sample. Even though we find that the SdHO also diminish at high tilt angles, this decay is qualitatively different from that of MIRO, possibly indicating a different physical origin.

Shubnikov-de Haas oscillations in high mobility GaAs quantum wells in tilted magnetic fields
We report on quantum magneto-oscillations in a high mobility GaAs/AlGaAs quantum well at very high (≥ 87◦) tilt angles. Unlike previous studies, we find that the spin and cyclotron splittings become equal over a continuous range of angles, but only near certain, angle-dependent filling factors. At high enough tilt angles, Shubnikov-de Haas oscillations reveal a prominent beating pattern, indica...
متن کاملEffective mass from microwave photoresistance measurements in GaAs/AlGaAs quantum wells
We have performed microwave photoresistance measurements in high mobility GaAs/AlGaAs quantum wells and investigated the value of the effective mass. The effective mass, obtained from the period of microwave-induced resistance oscillations (MIRO), was found to be about 12% lower than the band mass in GaAs, m b. In contrast, the measured magnetoplasmon dispersion (MPR) revealed an effective mass...
متن کاملTHE MASS OF THE ELECTRON IN GaAs/AlGaAs BY SHUBNIKOV-DE HAAS EFFECT AND THE SPIN-CHARGE LOCKING
The energy of the free electron gas is calculated in three dimensions. In this calculation an integral over the wave vector space occurs which was solved by Dingle. In the low temperature approximation the integral over the Fermi distribution leads to x/sinh x type expression, called the Dingle’s formula. The spin symmetry is found to modify this formula which determines the oscillation amplitu...

In a high mobility two-dimensional electron gas (2DEG) realized in a GaAs / Al0.3Ga0.7As quantum well we observe changes in the Shubnikov-de Haas oscillations (SdHO) and in the Hall resistance for different sample geometries. We observe for each sample geometry a strong negative magnetoresistance around zero magnetic field which consists of a peak around zero magnetic field and of a huge magnet...

In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been calculated as a function of confining frequency and mag...
