abstract="The temperature dependence of the energy relaxation time $\tau$e (T) of a two-dimensional electron gas at an AlGaAs/GaAs heterointerface is measured under quasiequilibrium conditions in the region of the transition from scattering by acoustic phonons to scattering with the participation of optical phonons. The temperature interval of constant $\tau$e, where scattering by the deformation potential predominates, is determined. In the preceding, low-temperature region, where piezoacoustic and deformation-potential-induced scattering processes coexist, $\tau$ e decreases slowly with increasing temperature. Optical phonons start to participate in the scattering processes at T\~{}25 K (the characteristic phonon lifetime was equal to $\tau$LO$\tau$4.5 ps). The energy losses calculated from the $\tau$e data in a model with an effective nonequilibrium electron temperature agree with the published data obtained under strong heating conditions.",
