Fermi liquid behavior of metallic 2D holes at high temperatures

Xuan P. A. Gao, A. P. Mills, A. P. Ramirez +2

The resistivity $\rho$ of high mobility dilute 2D holes in GaAs exhibits a peak at a certain temperature $T^{\ast }$ in zero magnetic field($B$=0). In the $T>T^{\ast }$ regime where d$\rho$/d$T<$0,…
