ZnO - nanostructures, defects, and devices
TL;DR: ZnO has received much attention over the past few years because it has a wide range of properties that depend on doping, including a range of conductivity from metallic to insulating (including n-type and p-type conductivity), high transparency, piezoelectricity, widebandgap semiconductivity, room-temperature ferromagnetism, and huge magneto-optic and chemical-sensing effects.
