摘要：

The anisotropic normal-state transport properties, resistivity and thermopower, are investigated for high-quality single crystals of La2-xSrxCuO4 in the compositional range 0.10 less-than-or-equal-to x less-than-or-equal-to 0.30. The results indicate that charge transport in the material with superconducting compositions is two-dimensional. A crossover from two to three dimensions is observed at high temperature or on entering the nonsuperconducting overdoped region.
