Abstract

We performed infrared magneto-photoluminescence (PL) spectroscopy on an InAs-inserted-channel InGaAs/InAlAs heterostructure. Series of Landau levels were clearly observed in the infrared PL spectra. From the energy separation between σ+ and σ- components of PL, the electron-hole g-factor in each Landau level were determined. We discuss the obtained Landau fan-diagram from the points that nonparabolicity of conduction band structure and penetration of electron wavefunction into InGaAs layer.
