“…If so, one would naturally expect a stronger A 0 (T ) in our ultra-high mobility sample, where the displacement contribution is suppressed, and a weaker τ q (T ). We note that such a scenario has been recently proposed to explain faster than T −2 -dependence of the inelastic relaxation at low T [57,58].…”

This scattering affects both the quantum lifetime, or the density of states, and the inelastic lifetime, which governs the relaxation of the nonequilibrium distribution function. Here, we report on MIRO in an ultra-high-mobility (μ>3 × 10 7 cm 2 /V s) two-dimensional electron gas at T between 0.3a n d1 .8 K. In contrast to theoretical predictions, the quantum lifetime is found to be T independent in the whole temperature range studied. At the same time, the T dependence of the inelastic lifetime is much stronger than can be expected from electron-electron interactions.
