The nominal value of x; the carrier density n (per a Ti site and per cm3) determined from Hall effect measurements; the resistivity ρ at 300 K and 5 K; the coefficient A in ρ~ AT2 below 40 K; the Hall mobility μ = n−1e−1ρ−1 at 5 K, where e is an elementary charge; and the superconducting critical temperature Tc for our Sr1−xLaxTiO3 single crystals
