Enhanced Energy harvesting, utilizing ZnO nanosheet based nanogenerator embedded in phononic crystal
MODARES JOURNAL OF ELECTRICAL ENGINEERING
In this report, we present a direct current piezoelectric nanogenerator based on ZnO nanosheets, which is driven by ultrasound waves propagating in water. ZnO nanosheets have been grown by hydrothermal method on Al layer as the bottom ohmic contact, while Ni layer serves as the top Schottky contact. Then, we have designed a 1D phononic crystal to realize localized standing wave at the position of nanogenerator, and consequently enhance the energy harvesting performance.
