(a) The resistivity of epitaxial LPNO films grown on STO (001) substrates as a function of temperature. The dashed lines are fits of data in the metallic region using Eqs. (1) and (3). Arrows indicate the temperature at which the upturn starts. (b) \(\rho_{0}\), \(\rho_{SAT}\) and n (inset) are the fitting parameters extracted from fitting curves and \(\rho \left( 0 \right)\) is the metallic resistivity extrapolated to 0 K. The region with the pink color indicates metallic behavior. The region with light blue represents a large upturn in resistivity.
