Strongly Enhanced Hole-Phonon Coupling in the Metallic State of the Dilute Two-Dimensional Hole Gas

X. P. A. Gao, G. S. Boebinger, A. P. Mills +3

We have studied the temperature dependent phonon emission rate $P$($T$) of a strongly interacting ($r_s\ge$22) dilute 2D GaAs hole system using a standard carrier heating techniqu…
