| Abstract Scope |
Calcium (0-30mol%) doped La(Cr0.2Co0.2Fe0.2Mn0.2Ni0.2)O3 High Entropy Perovskite Oxide (HEPO) materials are synthesized by the polymerizable precursor method (1). The impact of calcium doping at various levels on the unit cell, sintering, and electrical conductivity is studied. The electrical conductivity of the present materials is due to a p-type small polaron mechanism (2). X-ray Diffraction (XRD) was used to investigate the phase purity. Energy Dispersive X-Ray Spectroscopy (EDX) was utilized to evaluate the uniformity of the elements in the materials. A Scanning Electron Microscope (SEM) was used to investigate the sintering conditions further. The four-probe AC method was used for conductivity measurements. To analyze the surface characteristics and valence states of transition metals, X-ray Photoelectron Spectroscopy (XPS) was used. |
