Abstract :
Nonparabolic tendency of conduction subbands in InGaAs/InAlAs quantum wells (QWs), lattice-matched to InP, were studied using cyclotron resonance (CR) because its confinement potential was stronger than in InGaAs/InP and GaAs/GaAlAs QWs. Thickness of InGaAs well was 5–View the MathML source. Barrier thickness was more than View the MathML source. Field-scanned pulse CR and wavelength-scanned CR were observed. CR energy changed sublinearly with magnetic field. This curve agreed with our calculation, based on Kaneʹs three-level band theory and Landau quantization.
