**8. ZnO nano based applications**

The ZnO material is being used for many optoelectronic based devices applications. These devices applications include the varistors, sensors [13, 56–59], optical wave guides, UV light emitters [60], LEDs [61], micro-electro-mechanical systems [12], spin electronics [62], solar energies [63], p-n junctions [64], field effect and emissions [65–67], displays [68], acoustic waves [69], and solar cells [6].
