Zinc oxide (ZnO) ceramic substrate is a material that is used in various applications, including electronics, optoelectronics, and sensors. The properties of ZnO ceramics, such as high thermal stability, chemical stability, and good electrical conductivity, make them suitable for these applications.
ZnO ceramics can be synthesized using various methods, such as sol-gel processing, chemical vapor deposition, and sputtering. The crystal structure of ZnO ceramics is hexagonal, and they have a high surface area-to-volume ratio, which makes them suitable for use in various devices and systems that require a large active surface area.
In electronics, ZnO ceramics can be used as substrate material for transistors, field-effect transistors, and high electron mobility transistors. In optoelectronics, they can be used as the active material in light-emitting diodes and photodetectors. In sensors, they can be used as the sensing element in gas and humidity sensors, and in piezoelectric sensors.
In addition to their technological applications, ZnO ceramics also have environmental benefits, as they are biocompatible and non-toxic. This makes them suitable for use in medical devices and in various other applications that require biocompatibility and low toxicity.
