ZnO is important in nanotechnology for several reasons:
1. Wide Bandgap: ZnO has a bandgap of about 3.37 eV, making it suitable for high-frequency and high-power applications. 2. Piezoelectricity: ZnO exhibits piezoelectric properties, which are useful in sensors and actuators. 3. Biocompatibility: ZnO is non-toxic and biocompatible, which is essential for medical applications. 4. Photocatalysis: ZnO nanoparticles can degrade organic pollutants upon exposure to UV light, making them useful in environmental cleanup.
