Wide Bandgap: With a bandgap of 3.4 eV, ZnO is suitable for manifold blue and violet optoelectronic applications as well as UV devices.

Competitive Edge: The availability of large-size ZnO crystals offers a competitive advantage over other materials like GaN.

Optimal GaN Film Growth: ZnO substrates have a wurtzite structure with lattice constants well-matched to GaN, resulting in minimal lattice mismatch and optimal film growth.

Lattice Stress Absorption: ZnO is a soft compliant material that effectively absorbs lattice stress, protecting the growing GaN thin film.

Customized Solutions: Kingwin Optics offers customized high-quality ZnO crystal substrates and wafers to meet specific application requirements.

Applications: Optoelectronic Devices, UV Devices, Thin Film Growth, Research and Development, etc.
