Powder library of pseudo four components Li-Ni-Co-Ti compounds were prepared for exploring the composition region with the single phase of the layer-type structure by using combinatorial high-throuput preparation system “M-ist Combi” based on electrostatic spray deposition method. The new layer-type compounds were found wider composition region than the previous report. This process is promising way to find functional multi-component materials.

AbstractMgO and Mg1-xTixO thin films were deposited by the electrostatic spray deposition method using Mg(tmhd)2 and Ti(OiPr)2(tmhd)2 as source materials and tetrahydrofuran and 1-octyl alcohol as solvents. The refractive index of the films shows a strong change from 1.73 for MgO to 2.39 for TiO2. The optical band gap energy values are 3.83 eV for TiO2 film and higher than 5.1 eV for films of Mg/(Mg+Ti) > 0.67. The discharge voltage and current increased with a content of Ti in Mg1-xTixO films. All these changes are closely associated with different Mg/(Mg+Ti) ratios of the films.

Perovskite-type AxCa1-xByMn1-yO3-δ(A; La, Bi, Y, Sr) (B; Ni, Ti, V) thin films were prepared by the conventional electrostatic spray deposition (ESD) method in order to study which kind of substitution element show better thermoelectric property than AxCa1-xByMn1-yO3-δ. Electrical conductivity of the single-doped compound was increased when the substituted element was higher valence than Ca or Mn ion. PF value also showed similar tendency. Thermoelectric property of all compounds obtained the ESD method were consistent with the report of the solid-state reaction. Also, co-doped Bi0.02Ca0.98Mn0.98V0.02O3-δ and Bi0.02Ca0.98Mn0.98Ni0.02O3-δ showed relatively higher conductivity and PF value.

ABSTRACTWe established a Ca1-xBixMn1-yNiyO3 (0 ≤ x, y ≤ 0.1) powder library using a combinatorial system based on the electrostatic spray deposition method. Single phase perovskite-type structures were identified in all of the powders. To measure electrical conductivity, the powder library was subjected to high-pressure (200 MPa) and heat-treated at 950°C for 1 hour in an oxygen atmosphere. As a representative example, the electrical conductivity of 5%-Bi-substituted CaMnO3-δ showed a higher value (63 S·cm-1) than an unsubstituted powder (13 S·cm-1). The improved electrical conductivity, on the other hand, was still very far from the ideal result (167 S·cm-1).
