The rapid advancement in electronics and optoelectronics has opened new avenues for specialized materials, and Zinc Oxide (CAS 1314-13-2) is increasingly at the forefront. This inorganic compound, known for its white powder form, possesses a unique set of properties that make it highly valuable in the manufacturing of various electronic components. For companies in the electronics sector seeking innovative materials, understanding the potential of Zinc Oxide and sourcing it from a quality supplier is crucial.

Semiconducting Properties and Applications

Zinc Oxide is classified as a wide direct bandgap semiconductor, typically exhibiting n-type conductivity. Its bandgap of approximately 3.3 eV at room temperature, coupled with a high exciton binding energy, offers several advantages:

  • High Electron Mobility: This allows for efficient charge transport, vital for transistors and other active electronic components.
  • Transparency in Visible Light: While conductive, it remains transparent to visible light, making it ideal for transparent electrodes in displays and solar cells.
  • High Breakdown Voltage: Its wide bandgap enables it to withstand strong electric fields, suitable for high-power electronic devices.
  • Photoluminescence: ZnO can emit light efficiently when excited, leading to applications in light-emitting diodes (LEDs) and lasers.

These properties are exploited in a range of electronic devices:

  • Transparent Conductive Films (TCFs): Zinc Oxide, often doped with elements like aluminum (Al-ZnO), is used as an alternative to indium tin oxide (ITO) in touch screens, flat-panel displays, and flexible electronics. Its conductivity and transparency are key.
  • Gas Sensors: The electrical conductivity of Zinc Oxide changes upon exposure to various gases. This makes it an excellent material for sensing applications, used in devices to detect pollutants, flammable gases, and medical biomarkers.
  • Thin-Film Transistors (TFTs): ZnO-based TFTs are being developed for use in active-matrix flat-panel displays and other electronic circuits, offering potential advantages in low-temperature processing and performance.
  • Light-Emitting Diodes (LEDs) and Lasers: The strong luminescence of ZnO at room temperature makes it a candidate for UV and blue light-emitting devices.
  • Varistors: Zinc Oxide is a primary component in metal oxide varistors (MOVs), used for surge protection in electronic circuits.
