Abstract
We describe the screening of large combinatorial oxide libraries for determining their electric transport characteristics. Complete full ternary composition spreads of La2O3–Mn2O3–Co3O4 oxide alloys were deposited onto single conducting Nb-doped SrTiO3 substrates by the pulsed laser deposition technique incorporating a moving shutter and a rotating substrate holder. The electrical resistance of the spreads was determined using a custom-designed scanning conducting probe. We found that a single electrically conducting area in the ternary spread develops into two branches to LaMnO3 perovskites close to the ideal LaMnO3 stoichiometry and to a wide La0.65Co0.35OX–La0.20Co0.80OX system with perovskite-related structures. We also discovered that compositions along the tie line [La0.20Co0.65Mn0.15OX–La0.57Co0.20Mn0.23OX] exhibit the weakest temperature dependence and therefore could be used in fabricating of stable thin film resistors and gas sensors.
