CYCLOTRON TRANSITIONS AND ELECTRON MASS IN A WIDE INAS QUANTUM WELL IN STRONG MAGNETIC FIELDS

Abstract

The two-band model is used to calculate the cyclotron mass o f an electron in an InAs quantum well. The calculations were performed in the approximation o f infinity o f the depth o f the quantum well, taking into account the Landau level o f the second subband. It is shown that taking into account the cyclotron transition o f electrons within the second subband satisfactorily describes the experimental data obtained in strong magnetic fields in the heterostructure InAs/In0.81Ga0.19As/InxAl 1-xAs.
