Zinc oxide is a wide band-gap semiconductor material. It has broad potential applications in high-efficiency semiconductor photoelectronic devices, semiconductor photocatalysis and diluted magnetic semiconductors. Because of it lattice integrity, ZnO single crystals are essential for the fabrication of high-quality ZnO-based semiconductor devices. It is also an ideal substrate material for epitaxial growth of various thin films. MSE Supplies offers many options for ZnO crystals and substrates to meet customers' specific technical requirements. Please contact us to discuss your requirements with our scientists and engineers.
