Abstract
We report the measurement of the conduction band mass in n- type single 27-ML-wide InGaAs/InAlAs quantum well lattice matched to InP using two methods: (1) Magnetoluminescence spectroscopy and (2) far-IR cyclotron resonance. The magnetoluminescence method utilizes Landau level transitions between 0 and 14 T at 1.4 K. The far-IR cyclotron resonance measurements were made at 4.2 K and to fields as large up to 18 T. The 2D-carrier density N2D equals 3 X 1011 cm-2 at low temperatures. The magnetoluminescence technique yielded an effective conduction-band mass of mc equals 0.062m0 while the far-IR cyclotron resonance measurements gave mc equals 0.056m0. Both measurements show no evidence for any significant conduction-band nonparabolicity.
