Electronic phase diagram of La_(2-x)Sr_xCuO_4 thin films from Mott insulator to n-type metal probed by hall effect measurements

摘要

Electronic phase diagram of La_(2-x)Sr_xCuO_4 (LSCO) is discussed with respect to normal state Hall coefficients, R _H. We compare x dependence of R_H of LSCO measured at very high-field with that taken for the films that do not show superconductivity due to tensile strain.
