Linear temperature dependence of conductivity in Si two-dimensional electrons near the apparent metal-to-insulator transition

K. Lai, W. Pan, D. C. Tsui +3

In a high mobility two-dimensional electron system in Si, near the critical density, $n_c=0.32\times 10^{11}$cm${}^{-2}$, of the apparent metal-to-insulator transition, the conductivi…
