Band Parameters of MQWs Heterostructures InGaAs/GaAs: Magnetooptical Study

Abstract

Investigation of the optical absorption and magnetoabsorption spectra of a set of In(x)Ga(1-x)As/GaAs strained MQWs with different well widths and different Indium content x has been carried out at I .7 K in the presence of the magnetic field up to 7.5 T. The measurements performed on the free standing samples have allowed to obtain well-resolved oscillatory spectra and to reconstruct Landau level positions. An effective mass of the electron and other parameters of the InGaAs/GaAs MQW heterostructures depending on the Indium concentration were estimated.
