Abstract Scope |
Indium Gallium Zinc Oxide (IGZO) is a ceramic material used in optoelectronic technology, having essential results such as high efficiency in energy consumption and better image quality in display devices. On their side, high entropy ceramics (HECs) are relevant in many present studies due to some novel and better physical properties behavior. In this work, we studied the design of HECs with IGZO-based compounds by the solid-state method. Several trivalent and divalent cations are substituted in the layered crystal structure of IGZO, and the equilibrium of phases is studied under different compositions and high temperatures. The classic quenching method is used cooling to room temperature. Phase equilibrium was monitored using X-ray powder diffractometry (XRD) and scanning electron microscopy (SEM) to reveal microstructure and cation distribution with elemental mapping. In addition, the dielectric and optical properties will be obtained to analyze their possible applications. |
