At $T$=20mK, the resistivity of 2DHS shows an order of magnitude enhancement followed by a nearly perfect saturation above a characteristic field $B_P$ as $B_{||}$ increases, even with the $B$=0 conductivity of 2DHS as high as 75e$^2$/h. We demonstrate that $B_P$ extrapolates to zero at a finite hole density only at the lowest temperatures. Furthermore, we show that $B_{||}$ strongly suppresses d$sigma(T)$/d$T$, the slope of the $T$-dependence of conductivity, and even induces a sign change at sufficiently high $B_{||}$. The large magnetoconductivity induced by $B_{||}$ can not be fully accounted by the perturbative Fermi liquid interaction correction theory at intermediate $T$. | | Source: | arXiv, cond-mat/0506031 | | Services: | Forum | Review | PDF | Favorites | |
