Abstract

Shubnikov–de Haas oscillations in 150 Å single quantum wells of In_0.53Ga_0.47As/InP are detected without contacts, using a conventional electron paramagnetic resonance (EPR) spectrometer. The two‐dimensional properties of the signal are verified and the carrier concentration is deduced from the period of the oscillations. The effective mass m* = 0.041m_o obtained from the temperature dependence of the amplitude of the oscillations confirms that the signal originates from the In_0.53Ga_0.47As quantum well.
