We find a temperature dependent phonon-limited resistivity $ρ_{ph}(T)$ to be linear in temperature for $T\agt 50 K$ with the room temperature intrinsic mobility reaching values above $10^5$ cm$^2/Vs$. We comment on the low-temperature Bloch-Grüneisen behavior where $ρ_{ph}(T) \sim T^4$ for unscreened electron-phonon coupling.6 pages, 5 figuresMesoscale and Nanoscale Physicstext
