Acoustic phonon scattering of two-dimensional electron gas on (InAs)1(GaAs)1/InP heterointerfaces is observed by measuring electron energy loss rate, and is compared with that on GaInAs/InP heterointerfaces. The energy loss rate and effective mass of (InAs)1(GaAs)1/InP are obtained by analyzing Shubnikov–de Haas oscillation amplitude as a parameter of the electron temperature and lattice temperature. The resulting suppression of acoustic phonon scattering is due to the smaller deformation potential.
