Title: Resonance modulation of the intersubband electron-electron interaction in an AlSb({delta}-Te)/InAs/AsSb({delta}-Te) quantum well by magnetic field

Abstract

The amplitude-frequency modulation of oscillations of the magnetoresistance of 2D electrons in an AlSb({delta}-Te)/InAs/AsSb({delta}-Te) quantum well is studied. In the dependence of the amplitude of the oscillations {delta}(1/B){sub T=const}, regions of negative Dingle temperature are observed. The anomalies in the dependence {delta}(1/B){sub T=const} are attributed to the fact that the quantizing magnetic field resonantly induces intersubband electron-electron interaction between the 2D electrons of the ground size-quantization subband and excited subband. The resonance fields B and the times corresponding to the collision-related broadening of the Landau levels are estimated. The concentration threshold of filling of the excited size-quantization subband is established at a level of n{sub s} {approx} 8 x 10{sup 11} cm{sup -2}.
