(ZnO) Zinc Oxide wafers (A wide gap semiconductor material, 1cm x 1cm substrates are available)
Zinc Oxide is one of the potentially promised materials to produce echological semiconductor devices. Currently we provide double-surface polished substrates that sizes as 10mm x10mm x 0.5mm.
Orientation {0001} Zn-plane, {000-1} O-plane +/-30
Material and surface Hydrothermally grown ZnO single crystal
Both surfaces, Zn and O-plane as polished
Wafer size Squared shape 10 x10 x0.5mm
(With flatness at two corners; 2.45mm and 3.96mm)
