Zinc Oxide (ZnO) Thin Film on Si (100) Wafers

Zinc Oxide (ZnO) Thin Film on Si (100) Wafers

Overview
Our zinc oxide (ZnO) thin film wafers are fabricated on high-quality Si (100) substrates to provide uniform, high-quality semiconducting and functional oxide layers for research and device development.

ZnO is a wide bandgap semiconductor with excellent optical transparency, good electrical properties, and piezoelectric characteristics. These wafers are widely used in optoelectronics, sensor development, surface engineering, and thin film device research.
