Abstract

We report on millimeter wave measurements of an In_0.53Ga_0.47As/In_0.52Al_0.48As multiquantum well fabricated by gas source molecular beam epitaxy. Transmission experiments with the millimeter waves (16-110 GHz) were carried out as a function of the magnetic field up to 10 T at temperatures down to 0.6 K. The quantum oscillations corrresponding to the Shubnikov-de Haas effect are observed in the amplitude and phase of the transmitting waves. The effective mass can be estimated as 0.058m₀ for the 1st-subband electron. In spite of a small Fermi energy of 27 meV for the 1st subband, the enhancement of an effective mass is 30% over the bulk band-edge mass of 0.041m₀. The large difference originates from the resonant polaron coupling due to a fundamental GaAs-like LO-phonon in addition to the band nonparabolicity of the In_0.53Ga_0.47As well.
